[PATCH 2/5] CI: Refresh the Debian 12 arm32 cross compile container

[Andrew Cooper <andrew.cooper3@xxxxxxxxxx>]

From: Javi Merino <javi.merino@xxxxxxxxx>

Rework the container to user heredocs for readability, derive from
bookworm-slim and use apt-get --no-install-recommends to keep the size down.

Convert it to being a non-root container.  Add checkpolicy as FLASK is an
available build option for arm32 under Randconfig testing.

Rename the CI jobs to debian-12-arm32-* to follow the naming scheme of all the
other CI jobs.

No functional change.
