On Debian 13 (Trixie), libvirt packaging is modularized and the libvirt-daemon-lock package (providing virtlockd) is optional. The evacuate hook previously assumed all libvirt services were installed and failed when stopping/starting missing units. Extract a reusable manage_libvirt_service.yaml task file that checks if a service exists via systemctl list-unit-files before managing its units. This prevents failures when optional libvirt packages are not installed and future-proofs against further packaging changes.
