Namhyung Kim ff898552fb perf synthetic-events: Ignore dead threads during event synthesis ...

When it synthesize various task events, it scans the list of task
first and then accesses later.  There's a window threads can die
between the two and proc entries may not be available.

Instead of bailing out, we can ignore that thread and move on.
