    build: disable libnm-glib support by default
    
    By now nobody should be using this. Keep the code around for a little
    longer just in case anybody still uses this.
    
    The libnm-glib support also serves as an example how do we build two
    different versions of the properties plugin. We'll soon be in a similar
    situation with Gtk 4.0. (sigh.) Just don't drop it yet.
