[gnome-software] Add a simple GSettings file with the compatible desktops listed

[Richard Hughes <rhughes src gnome org>]

commit c6847fc8a8b624d80e72e41dbed4d0665213a6dd
Author: Richard Hughes <richard hughsie com>
Date:   Mon Nov 4 10:19:18 2013 +0000

    Add a simple GSettings file with the compatible desktops listed
    
    Setting this is easier than setting an environment variable, and also allows
    us to have a different upstream / distributor default.
