make-firmware-image: implement firmware/dep11 generation for bookworm and above 

Mimic what make_disc_trees.pl does, making it possible for hw-detect to
spot not only the /firmware/dep11 directory in netinst images, but also
on installation images with firmware added manually.

Rename pseudo-option to clarify it returns filenames and indices.

Keep generation disabled for bullseye (as an extra safeguard, even if we
have separate, per-release branches anyway): That's helpful information
but bullseye is a stable release, and changing even unofficial material
might not be the best idea. Be cautious by default, it's easy enough to
enable if desired.
