perf evsel: 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. The attr->task is to track task related events (fork/exit) only but other meta events like comm and mmap[2] also needs the task events. So setting attr->comm and/or attr->mmap causes the kernel emits the task events anyway. So the attr->task is only meaningful when other bits are off but I'd like to set it for completeness.
