[gtk+/pathbar] Initialize home/desktop/root in init(), not in set_file_system()

[Federico Mena Quintero <federico src gnome org>]

commit 1711baad5814a9c3057de20fd44ec46e7010c655
Author: Federico Mena Quintero <federico gnome org>
Date:   Mon Apr 29 17:12:37 2013 -0500

    Initialize home/desktop/root in init(), not in set_file_system()
    
    We want to get rid of that gtk_path_bar_set_file_system() API, so we'll
    initialize the basic folders at initialization time.
