Cédric Bosdonnat bd773e74f0 LXC: workaround machined uncleaned data with containers running systemd.
The problem is described by [0] but its effect on libvirt is that
starting a container with a full distro running systemd after having
stopped it simply fails.

The container cleanup now calls the machined Terminate function to make
sure that everything is in order for the next run.
