sysutils/cpu-microcode-intel: Handle extended signature tables
Intel microcode files can contain an extended signature table after the
main payload, listing additional processor signatures and platform flag
combinations that are covered by the same microcode blob.
ucode-split was only reading the primary header signature when naming
output files and ignored the extended table entirely. As a result,
processors whose signature appeared only in an extended table entry had
no matching split file in ${DATADIR} and therefore no microcode via
cpucontrol(8).
This affected a number of CPU families in the current release, including
Raptor Lake (06-bf-02/05/06/07, Core Gen13/Gen14), Sapphire Rapids
steppings E0-E3 (06-8f-04 through 06-8f-07), Arrow Lake-H (06-c5-02),
Panther Lake (06-cc-02/03), and others.
Extend ucode-split to read the extended signature table and write an
additional output file for each entry.

deskutils/caja-extensions: switch to GitHub source
Switch from MATE mirror to GitHub tarball using USE_GITHUB and
GH_ACCOUNT=mate-desktop, remove tar:xz, bump PORTREVISION, and
remove stale gtk-doc plist entries.
archivers/engrampa: switch to GitHub source
Switch from MATE mirror to GitHub tarball using USE_GITHUB and
GH_ACCOUNT=mate-desktop, and add autoreconf.
universe: emit warning instead of error for bad/missing KERNCONF
When doing a large `make universe` build with multiple KERNCONFS,
it should not be an error when a particular target has a missing
KERNCONF.
In this example,
```
$ make universe TARGETS='arm64 riscv' KERNCONFS='QEMU VIRT'
```
Currently, arm64 does not have a QEMU conf, and riscv
does not have a VIRT conf. However, this command should still
succeed instead of failing with the following message:
```
make[2]: /usr/src/Makefile:767: Target architecture for riscv/conf/VIRT unknown. config(8) likely too old.
in .for loop from /usr/src/Makefile:761 with kernel = VIRT
