[pygi] Don't set a default constructor for structures.

[Simon van der Linden <svdlinden src gnome org>]

commit b4189be2b2d3c350fdf33e27309bee5a72e4f72a
Author: Simon van der Linden <svdlinden src gnome org>
Date:   Fri Jan 8 20:33:44 2010 +0100

    Don't set a default constructor for structures.
    
    Update tests accordingly.
    
    The reason for this change is that setting __new__ in the metaclass doesn't let
    one overrides it afterwards, in a subclass (in my experience, at least, even
    though it seems weird).
