Chunxin Zang 4453deacf4 perf sched: Fix sched latency analysis incorrection when using 'sched:sched_wakeup' 
'perf sched latency' is incorrect to get process schedule latency when
it used 'sched:sched_wakeup' to analysis perf.data.

Because 'perf record' prefers to use 'sched:sched_waking' to
'sched:sched_wakeup' since commit d566a9c2d4 ("perf sched: Prefer
sched_waking event when it exists"). It's very reasonable to evaluate
process schedule latency.

Similarly, update sched latency/map/replay to use sched_waking events.
