[pygobject] Remove pygtk_version attribute from internal gi._gobject module.

[John Palmieri <johnp src gnome org>]

commit 11c45ac6dcb6ffad766d03bfc77f45a6d703a90d

    Remove pygtk_version attribute from internal gi._gobject module.
    
    This used to be provided for backwards compatibility with older PyGTK
    versions. As PyGObject3 no longer provides support for static bindings
    like PyGTK, the pygtk_version attribute has become obsolete.
