perf test: Add trace record and replay test



It just check trace record and replay could display correct output.
It uses 'sleep' process and sees there's a clock_nanosleep syscall.

  $ sudo perf test -vv replay
  108: perf trace record and replay:
  --- start ---
  test child forked, pid 1563219
  [ perf record: Woken up 1 times to write data ]
  [ perf record: Captured and wrote 0.077 MB /tmp/temporary_file.w1ApA (242 samples) ]
       0.686 (1000.068 ms): sleep/1563226 clock_nanosleep(rqtp: 0x7ffc20ffee10, rmtp: 0x7ffc20ffee50)           = 0
  ---- end(0) ----
  108: perf trace record and replay                                    : Ok
