Subject: [PATCH 7/7] perf tools: Set attr.task bit for a tracking event

The perf_event_attr.task bit is to track task (fork and exit) events
but it missed to be set by perf_evsel__config().  While it was not a
problem in practice since setting other bits (comm/mmap) ended up
being in same result, it'd be good to set it explicitly anyway.
