perf_events: Fix FORK events
Commit 22e19085 ("Honour event state for aux stream data") introduced a bug where we would drop FORK events. The thing is that we deliver FORK events to the child process' event, which at that time will be PERF_EVENT_STATE_INACTIVE because the child won't be scheduled in (we're in the middle of fork). Solve this twice, change the event state filter to exclude only disabled (STATE_OFF) or worse, and deliver FORK events to the current (parent).
