thumbnail: Use new glib attributes to get the thumbnails for x/xx largewip/corey/thumbnail-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.
