Frederic Weisbecker dd833d713c perf: Do the comm inheritance per thread in event__process_task 
event__process_task() doesn't propagate the comm copy on clone,
but only on process fork. So we loose all the tid:comm resolution
for tasks that aren't a main process thread.

Progragate the per thread granularity to event__process_task for
pid resolution.

This fixes various unresolved pids in perf sched, especially when
we trace multithread processes. The problem is quickly reproducible
with the messaging benchmark using the multithread mode "-t" :

	perf sched record perf bench sched messaging -t
