    app: core/gimpmarshal.h is generated after building in app/config/.
    
    It is a little fuzzy whether expected or not, architecturally-wise. On
    one hand, I can see some core/ header includes under config/. Though on
    the other hand, app/Makefile.am explicitly sorts config/ below core/.
    Anyway let's just use g_cclosure_marshal_VOID__VOID which is the same as
    gimp_marshal_VOID__VOID and get rid of the include.
    This fixes builds from scratch.
