[gdk-pixbuf/drop-x11] Drop gdk-pixbuf-xlib

[Emmanuele Bassi <ebassi src gnome org>]

commit f9dc2d9a26ffb72c8258dbf72ae406420d663081
Author: Emmanuele Bassi <ebassi gnome org>
Date:   Sat Oct 19 16:20:51 2019 +0100

    Drop gdk-pixbuf-xlib
    
    The separate gdk-pixbuf-xlib API and shared library has been deprecated
    for years, and is not even built by default; it has been moved out of
    tree, into its own repository, in case people still depend on it.
