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.
