package/gdk-pixbuf-xlib: new package

Deprecated Xlib integration for GdkPixbuf.

gdk-pixbuf-xlib has been deprecated and split off of gdk-pixbuf since
version 2.42.0 and
https://gitlab.gnome.org/GNOME/gdk-pixbuf/-/commit/3362e94c2595440f322798dc4d15f1ed24a4c52c
resulting in the following "hidden" warnings with xscreensaver since
commit a7b51ed3013c919b293deb95299e33363fb9df70:

   Warning: GTK version 2.24.33 was found, but at least one supporting
            library (gdk-pixbuf-xlib-2.0) was not, so GTK can't be used.
            Perhaps some of the development packages are not installed?

   Warning: The GTK libraries do not seem to be available; the
            `xscreensaver-demo' program requires them.

   Warning: The GDK-Pixbuf library was not found.

            The PNG library is being used instead.

            Some of the demos will not use images as much as they could.
            You should consider installing GDK-Pixbuf and re-running
            configure.
