[gtkmm/gtkmm-2-22] Style: Fix the clone_vfunc() implementation.

[José Alburquerque <jaalburqu src gnome org>]

commit 8f1662f7c227a72566106c94d48dfd8a5ea269be
Author: José Alburquerque <jaalburqu svn gnome org>
Date:   Fri Nov 5 16:31:35 2010 -0400

    	Style: Fix the clone_vfunc() implementation.
    
    	* gtk/src/style.hg: Modify the clone_vfunc() to take an extra
    	reference of the GtkStyle obtained from the base class.  This is so
    	that the clone_vfunc_callback() does not lose its last reference after
    	it executes.
    
    	Fixes GNOME Bug #633975 (mario).
