utmp: turn systemd-update-utmp-shutdown.service into a normal runtime service

With this change systemd-update-utmp-shutdown.service is replaced by
systemd-update-utmp.service which is started at boot and stays around
until shutdown. This allows us to properly order the unit against both
/var/log and auditd.
