libvirtd was being restarted on the controller during negative
evacuation tests that rely on the service being to cause an
evacuation failure.
This change adds various virt services to the list of services stopped
and now disabled on the host to ensure these don't cause systemd to
restart libvirtd:
* virtlogd.service
* virtlogd-admin.socket
* virtlogd.socket
* virtlockd.service
* virtlockd-admin.socket
* virtlockd.socket
