[pygobject] foreign: Register cairo.Path and cairo.FontOptions foreign structs

[Martin Pitt <martinpitt src gnome org>]

commit b21f66d2a399b8c9a36a1758107b7bdff0ec8eaa
Author: Bastian Winkler <buz netbuz org>
Date:   Wed May 9 19:04:01 2012 +0200

    foreign: Register cairo.Path and cairo.FontOptions foreign structs
    
    They are rarely used, but they are used at least by Gdk, PangoCairo and
    Clutter.
    
    clutter.Path is not used by any API that the test suite uses, so leave that
    without a test for now.
