update sys:get_status/2,3 documentation for gen_event

Modify the documentation for the sys:get_status/2,3 functions to reflect
that they also work on gen_event processes, and add a cross reference for
gen_event:format_status/2 to go along with the existing cross references
for gen_server and gen_fsm.
