mutter: Disable session management with mutter and gnome-kiosk
We run the compositors directly, not going through the GNOME session manager, so it's not even worth trying to connect to the session manager at startup.
Add --sm-disable
to the mutter and gnome-kiosk command line to avoid
errors when trying to connect to the session manager.
