[gdk-pixbuf] Build gdk_pixbuf_get_toplevel() even if !USE_GMODULE

[Matthias Clasen <matthiasc src gnome org>]

    Build gdk_pixbuf_get_toplevel() even if !USE_GMODULE
    
    a55aa6eb introduced gdk_pixbuf_get_toplevel(), which is called if
    GDK_PIXBUF_RELOCATABLE but is only built if USE_GMODULE &&
    GDK_PIXBUF_RELOCATABLE.  This causes build failures on MinGW and Darwin
    when configured with --disable-modules.
