ci/images: drop the LXC images

Last use case was dropped in 36b08eb30387,
and I don't expect we'd use this in future anymore.
The "bullseye" in README was clearly a typo (it's the codename for 11).

-### debian-bullseye
+### debian-buster (10)
 
 Used to serve the same purpose as `debian-11`. As of 2022-03-09, it is still
 used by some jobs (linters).
 
-### lxc-debian-11

-Very similar to the main image. The main difference is a custom base image
-which can be used for LXC runners and boots into systemd. It is useful to
-update it when `debian-11` gets updated, as it will allow some of the tests to
-be migrated to the LXC runners in the future (especially the
-unstable/problematic ones - pytests already migrated, deckard might be a good
-candidate).

 ## Maintenance
 
 The `ci/images/` directory contains utility scripts to build, push or update
