    udisks2: Set G_VOLUME_IDENTIFIER_KIND_CLASS identifier for volumes
    
    This identifier was discussed in
    
     https://bugzilla.gnome.org/show_bug.cgi?id=668295
    
    and added to GLib with this commit
    
     http://git.gnome.org/browse/glib/commit/?id=10fbfcf09010e423cfc79c54e8da50b62a0f4b8a
    
    For now, we do the ifndef dance instead of hard-requiring GLib master.
