    wacom: Add scenario tester
    
    Running the helper will launch gnome-control-center with a mocked Wacom
    Cintiq tablet through umockdev when one isn't present or easily available.
    
    The Cintiq was selected as it will trigger showing all the different
    buttons Wacom tablets can make the panel spawn.
