    gnu: gdk-pixbuf: Add a search path for the loaders cache file.
    
    Fixes <https://issues.guix.gnu.org/50957>.
    
    The previous commit added a profile hook to compute a gdk-pixbuf loaders 
cache
    file.  This change enables gdk-pixbuf to make use of it.
    
    * gnu/packages/gtk.scm (gdk-pixbuf)[native-search-paths]: Add a search path
    specification to set the GDK_PIXBUF_MODULE_FILE environment variable.
