[pygobject] Unify unichar to Python GI marshaling code

[Simon Feltman <sfeltman src gnome org>]

commit 03ff41ae4bb83858338d96cc6210092c7fb82464
Author: Simon Feltman <sfeltman src gnome org>
Date:   Thu Mar 28 05:10:45 2013 -0700

    Unify unichar to Python GI marshaling code
    
    Change _pygi_argument_to_object to use the cachers marshaler
    (_pygi_marshal_to_py_unichar) directly instead of keeping a
    copy of the code.
