Server Bug fix: Make D-Bus introspection work again.

* mandos (DBusObjectWithObjectManager.Introspect): Bug fix; call
                                                   method Introspect,
                                                   not class
                                                   DBusObjectWithAnnotations.
  (alternate_dbus_interfaces/wrapper/fixscope): Make wrapped D-Bus
                                                signal function look
                                                like a D-Bus signal so
                                                Introspect can see it.
