systemd: Augment Requires/Wants with After

Browse Source 
Requires/Wants only tells systemd that the corresponding unit
should be started when the current one is, but that could very
well happen in parallel. For virtlogd/virtlockd, we want the
socket to be already active when the hypervisor driver is
started.
