[pygobject] Remove legacy docs

[Christoph Reiter <creiter src gnome org>]

commit 3aa5c80213194a8a3a993e937bae0f6b3d992547
Author: Christoph Reiter <creiter src gnome org>
Date:   Tue Jan 24 22:05:48 2017 +0100

    Remove legacy docs
    
    They aren't shipped, can't be build and describe the old
    pygobject 2 interface.
    
    There also was a doc-dist make target, but it was broken.
    
    If someone wants to look things up they are in git or still
    online for 2.28: https://developer.gnome.org/pygobject/stable/
