[4.0] Use system_settings_add_changed_cb

Before changing, we use system_settings_set_changed_cb to get notice
when system language is changed.

But system_settings_set_changed_cb can be called once in one process so
it can make problem.

Change system_settings_set_changed_cb to system_settings_add_changed_cb.
