    gnetworkmonitornm: Stop using removed PropertiesChanged signal
    
    Use the org.freedesktop.DBus.Properties interface to listen
    to PropertiesChanged signals on /org/freedesktop/NetworkManager.
    
    NetworkManager used to provide its own legacy PropertiesChanged
    signal, but that was dropped in
    https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/merge_requests/853
    
    This requires NetworkManager >= 1.2 (2016)
    
    Fixes: #2505
