    thumbnail: Use new glib attributes to get the thumbnails for x/xx large
    
    When in the introduction of x-large and xx-large thumbnails in
    278435e3c20244b48986c6cd8b72c5317668c72d, we no longers retrieved the
    thumbnails correctly, because glib/gio was only looking for normal and
    large thumbnail paths.
    
    glib!2918 introduces new attributes for x-large and xx-large
    thumbnails paths.  Produce the correct file attribute depending
    on the size thumbnail we are generating.
