Ján Tomko 12ee0b98d3 Check if systemd is running before creating machines
If systemd is installed, but is not the init system,
systemd-machined fails with an unhelpful error message:
Launch helper exited with unknown return code 1

Currently we only check if the "machine1" service is
available (in ListActivatableNames).
Also check if "systemd1" service is registered with DBus
(ListNames).

This fixes https://bugs.gentoo.org/show_bug.cgi?id=493246#c22
