CI: Upgrade from Debian 11 'bullseye' to Debian 12 'bookworm'

Debian 11 is EOL for normal security support, and doesn't ship dbus
1.14.x anyway. Do our acceptance testing in Debian 12, which is not EOL,
and does include dbus 1.14.x.

Drop the buster build altogether: it is EOL, even for Debian LTS.
