pf: Send syncookies from the receiving thread
pf sends outbound packets by offloading them to a single per-vnet SWI handler
through the `V_pf_sendqueue` mbuf queue. A large DDoS attack may overwhelm
that per-vnet queue with syncookie packets and cause contention in the SWI
handler that negatively affects other pf operations.
Fix this by sending the initial syncookie challenge from the context
of the receiving thread. This avoids the syncookie-induced contention on
the `pf_intr` mbuf queue.

misc/codex: Directly use install command instead of CARGO_INSTALL_PATH
Using the ports framework's install target (from cargo.mk) with
CARGO_INSTALL_PATH specified seems to run build again, which consumes
too much time, even when the build phase has successfully finished. To
avoid that, use custom do-install target with install command.
While here, remove extraneous binary (logs_client) from installation.

sys/tests/kern/pdopenpid: pdopenpid(2) is allowed in cap mode
Adjust test to check for ECAPMODE using grandchild instead of child.
Childrens can be opened even in cap mode. Add test for the later.

pdptrace(2): allow debugging in capability mode
The pdopenpid(2) syscall is allowed in capability mode. Add the chicken
switch security.bsd.ptrace_in_cap_mode, which disables it without
reboot, if needed.
The descriptor passed to pdptrace(2) must have the CAP_PTRACE
capability enabled. This capability is not enabled by default by
pdfork()/pdopenpid(), and the calls do not return a procdesc suitable
for debugging. The opening code must prepare for debugging in advance by
passing the PD_PTRACE_CAP flag to pdfork()/pdopenpid().
For ptrace(2), allow PT_CLEARSTEP and PT_GET_CHILDREN for the current
thread and process in cap mode as well.

pdopenpid(2): allow in capability mode with restrictions
The pdopenpid() syscall is allowed to open processes which are either
direct children of the caller, or are debuggees already attached to the
calling process. This is reasonable because we could have controlled the
child on fork anyway.
The procdesc-less debuggee can legitimately appear due to ptrace
FOLLOW-FORK mode.
