Subject: [PATCH] CI VMs: bump, to debian with cgroups v2

Per consent in 2024-03-20 Planning, remove support for cgroups v1.
And, per discovery on 2024-05-28, systemd 256 no longer even
boots on a cgroups v1 system.

This commit switches to VMs built in:

  https://github.com/containers/automation_images/pull/338

...in which Debian is now cgroups v2 with crun.

Requires disabling two conformance tests which fail when run
against docker 26.1; see #5526 for context on those.

Also requires disabling two bats tests on debian because
something changed there in ulimits. I'll look into them
later but right now this gives us breathing space.

And, latest git on f40 refuses to serve non-root files when
run as root ("dubious ownership"); so, in start_git_daemon(),
chown the extracted files.
