[pygobject/gi-boxed-remove-del] Remove GObject.Value.__del__

[Christoph Reiter <creiter src gnome org>]

commit b36da092aa96787dbc797a860d5b243ccfc0d6bd
Author: Christoph Reiter <reiter christoph gmail com>

    Remove GObject.Value.__del__
    
    We can move this into tp_dealloc now.
    Only call unset() in the slice allocate case since g_boxed_free() will
    do it anyway.
