live: support systemctl to enable *dm

systemd is a tricky beast: getting it to actually launch gdm required considerable effort on the part of stupid myself. The relevant links: * https://wiki.archlinux.org/index.php/Systemd#Running_DEs_under_systemd * http://unix.stackexchange.com/a/35626/15296 Still looks pretty dirty, and there's some duplication with a hook in features.in/slinux as well.
