Fix autopkgtest integration test in bookworm (#1092670)

Heads-up: I've tested this MR on Jan 8 at it fixed autopkgtests for bookworm. However, due to upstream changes in the API (https://bugs.debian.org/1092987), the tests fail on a different issue now.

dnsmasq contains the systemd units to start dnmasq as a daemon. As such, when vagrant-libvirt tries to start a new instance, it fails, due to the socket already being in use. This previously didn't show because dnsmasq 2.89 had very loose error checking in that regard.

The solution is to just install the base package which contains the binary needed, without starting dnsmasq as a service.
