shell-util: Only use systemd if gnome-shell is managed by systemd

Browse source 
Simply looking at the return value of sd_pid_get_user_unit can be used
to determine if the process is in a systemd unit, but it doesn't say if
gnome-shell is managed by systemd.

For example, running toolbx on a host with systemd creates a libpod
unit, even if the gnome-shell that gets started in the toolbx is itself
not managed by systemd.

We can make sure that gnome-shell is managed by systemd simply by
checking if the unit we're running starts with org.gnome.Shell.
