vm: disable/enable qubes-vm@ service when domain is removed/created

Browse Source 
If domain is set to autostart, qubes-vm@ systemd service is used to
start it at boot. Cleanup the service when domain is removed, and
similarly enable the service when domain is created and already have
autostart=True.

Fixes QubesOS/qubes-issues#4014
