[gnome-control-center] Add a simple AppData file

[Richard Hughes <rhughes src gnome org>]

    Add a simple AppData file
    
    This is needed for three reasons:
    
     * To be able to arrange the icon into a folder in GNOME Software
     * So that we do not allow the application to be removed
     * To show the update description not in the 'OS Updates' package section
