patches: libvirt: Use "libvirt" unix_sock_group

Now that libvirt 3.6 is used on kvm nodes (via UCA repos), which
by default uses "libvirt" group for socket ownership,
change old "libvirtd" in salt-formula-libvirt's:
- libvirt/files/libvirtd.conf.Debian

This allows us to remove the manual group creation from VCP state
file, which was not re-entrant (failed if group already existed).
