Make sure not to get a double directory separator in case the home

	* gtk/gtkrc.c (gtk_rc_append_default_module_path): Make sure not
	to get a double directory separator in case the home directory
	ends with one. This would cause trouble especially on Windows,
	where the path will be confused with the syntax for an an UNC
	(network share) path \\server\share\path.
	(gtk_rc_add_initial_default_files): Ditto.
