tests: update most Debian images to Bookworm

tests: update most Debian images to Bookworm

Bookworm has been out a while now. Time to update our containers to
the current stable. This requires the latest lcitool repo so update
the sub-module too.

For some reason the MIPs containers won't build so skip those for now.
We also have to skip the armel builds due to a stuck libc update.
