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
