[gnome-menus] Remove gmenu_tree_directory_get_tree()

[Vincent Untz <vuntz src gnome org>]

commit 52f9f7017779b6691e2b3f46f6c24e37f219abbf
Author: Colin Walters <walters verbum org>
Date:   Sun Apr 17 11:22:32 2011 -0400

    Remove gmenu_tree_directory_get_tree()
    
    This causes a circular reference internally, and API consumers
    can just keep track of it easily enough externally.
