[gtk: 1/3] GtkFileFilter: Add a GObject property for the name

[Timm Bäder <baedert src gnome org>]

commit b83caec6b987930fe4bfd51128595970a54aa107

    GtkFileFilter: Add a GObject property for the name
    
    The name field was previously not a property, which meant you couldn't set in in
    GtkBuilder as translatable.
