[gdk-pixbuf] Move the API reference down two levels

[Emmanuele Bassi <ebassi src gnome org>]

commit b4acb66c1e026fc3cd8a6d1ac961f68fb6fb91e2
Author: Emmanuele Bassi <ebassi gnome org>
Date:   Sun Apr 29 00:57:56 2018 +0100

    Move the API reference down two levels
    
    The `docs` directory is empty, and gdk-pixbuf is not part of GTK any
    more, so there's no point to have the API reference under a separate
    directory.
