pw: remove mail file with unlinkat instead of building a path
This is consistent with how at jobs and crontabs are removed.

pw: remove crontab with unlinkat instead of spawning crontab
crontab -r only unlinks the crontab file, so spawn it directly with
unlinkat() relative to conf.rootfd. This also makes the crontab
removal work with pw -R.

pw: fix at job removal when deleting a user
rmat() used stat() with a path relative to the current working
directory, so it never found the job files in /var/at/jobs and the
at(1) jobs of a deleted user were never removed.
ef7d0eb9489f also broke it by introducing a typo: /usr/sbin/atrm instead
of /usr/bin/artm.
Use fstatat() with the directory fd to stat the job files relative to
the at jobs directory, and unlinkat() them directly instead of spawning
atrm.
Those changes allow us to make it works with pw -R.

linux: implement prctl PR_{G,S}ET_THP_DISABLE
Since we don't have THP in FreeBSD, return that it's disabled. Linux
applications use this to get around the weird latency spikes THP in
Linux creates. Since FreeBSD superpages don't suffer from this issue,
just say it's disabled.
This removes the noisiest noise from the linux claude running on
FreeBSD.

tests: skip gracefully when the tested binary's own package isn't installed
pkgbase splits programs and their tests into separate packages (e.g.
unifdef/yacc/indent/file2c -> toolchain, jail -> jail, etc), while their
tests always land in the generic tests package. Installing just the
tests package therefore leaves these suites unable to find the binary
they exercise, and they fail confusingly instead of skipping.
Rather than force all packages to be installed for the tests package,
make the tests cope with the missing packages. Add require.progs (or,
for TAP/PLAIN-style suites with no atf_set hook: TEST_METADATA
required_programs) for the binary under test in: bectl, certctl,
ctfconvert, dhclient, file2c, indent, ipfw, jail, lastcomm, mixer,
newsyslog, nvmecontrol, pfctl, praudit, sa, syslogd, tunefs, unifdef,
yacc, ztest.
I skipped adding data for all the binaries in the base runtime
package for simplicity.

man: Do glob expansion with echo instead of ls
echo is a shell builtin, and always present. While ls usually works,
some upgrade scenarios need to have ls be a build to to work
correctly. Rather than add it as a build tool, use echo instead which is
always safe because sh is a build tool.

da: Stop the probing when periph invalidated in dadone_proberc
When READ CAPACITY fails, we call cam_periph_invalidate() for some
hopeless ASC/ASCQ combinations and then fall through to test the cache
state. This results in excess commands to the abandoned device that may
take a while to timeout and/or report confusing errors. Instead, call
daprobedone() when the periph is invalid to terminate the probe.

stand/efihttp: Support arbitrary http[N]://host[:port]/path devspecs
Until now, the "http" device only worked when firmware itself booted
loader.efi via EFI HTTP Boot: efihttp_dev_init() required a URI node on
the loader's own boot device path, and every fetch went to that same
server. Add a second form, using the parse_uri() helper from libsa/dev.c,
that works anywhere: http[N]://host[:port]/path (N is a network interface
unit, defaulting to 0). This lets a devspec like this be used as rootdev,
in loader.conf, or interactively, independent of how loader.efi itself
was booted.
Network configuration is shared, loader-wide state (the myip/netmask/
gateip/nameip globals from net.h): if something has already configured
them (e.g. tftp/nfs via net_open()), the http device just reuses those
values, applying them to EFI_IP4_CONFIG2_PROTOCOL as a static address. If
nothing has, it drives IP4Config2's own DHCP directly instead of calling
netdev's net_open(): net_open() opens the NIC's SNP
EFI_OPEN_PROTOCOL_EXCLUSIVE, which would disconnect the Mnp/Ip4/.../
HttpDxe driver chain this code depends on. That chain is also commonly
