systemctl: make sure "systemctl -M status" shows cgroup tree of container not host

This shows the cgroup tree of the root slice of the container now, by
querying the cgroup pid tree via the bus instead of going directly to
the cgroupfs.

A fallback is kept for really old systemd versions where querying the
PID tree was not available.

Fixes: #20958
