Use debian-trixie

Replace debian-bookworm with debian-trixie for the base job in order
to use a newer version of qemu that has patch [0] that addresses an
issue where test_boot_cloned_encrypted_volume fails when run on a
fast machine.

The default python in debain-trixie is Python 3.13, which is a supported
python version for the Gazpacho development cycle [1].

Also, updated the package prereq file for some necessary packages that
aren't included by default in trixie.
