src/backend-dbus/actions.c: Fix MATE lockdown supportpersonal/sunweaver/mate-lockdown-support

Don't require org.gnome.desktop.lockdown gsettings to be set, honour
org.mate.desktop.lockdown gsettings instead when running on MATE
desktop.

If not on MATE and not on GNOME (or similar) then don't check the
lockdown settings at all.
