Return callback module in supervisor format_status
The previous implementation of supervisor:get_callback_module/1 used sys:get_status/1 to get the supervisor inner state and retrieve the callback module. Such implementation forbids any other supervisor implementation that has an internal state different than the #state{} record in supervisor.erl. This patch allows supervisors to return the callback module as part of the sys:get_status/1 data, no longer coupling the callback module implementation with the inner #state{} record. Notice we have kept the clause matching the previous sys:get_status/1 reply for backwards compatibility purposes.
