[gtk: 1/2] Annotate GtkTreeModelSort.new_with_model() appropriately

[Emmanuele Bassi <ebassi src gnome org>]

    Annotate GtkTreeModelSort.new_with_model() appropriately
    
    The new_with_model() method is a constructor, and it returns a GtkTreeModelSort
    instance, even if the C API returns a GtkTreeModel for the convenience of C
    developers.
    
    Fixes: #1077
