    installed-media: Special gnome-continuous images support
    
    This patch links gnome-continuous images to appr. libosinfo's OS entry
    so that Boxes gives it a nice name and assign supported devices. This
    also fixes the issue of nonfunctional networking in VM created for these
    images.
    
    Ideally we shouldn't need to do this ourselves and libosinfo should do
    the detection/mapping or we should look into libguestfs for this but
    that would be a lot of work and it will not be very useful when we add
    support for OVF files and gnome-continuous start to produce those. So
    for now we go with this hack, which is not a that bad.
