Update submodules and add missing ones, as needed

It's been a while since we did a full reproducible build via the
releng tree.  Some of the old modules are now obsolete, and a couple
of the new ones weren't present.

This is an initial test after updating the existing submodules and
adding the missing ones.  I don't really expect it to work, it's a
first attempt.

At minimum, we should go through and clean out submodules we no longer
use, but that can wait until we figure out if we now have all the
right modules and branches recorded here and whether the resulting
configuration works properly.
