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 d566a9c2d482 ("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.
