perf test: Add test for Intel TPEBS counting mode

Intel TPEBS sampling mode is supported through perf record. The counting mode
code uses perf record to capture retire_latency value and use it in metric
calculation. This test checks the counting mode code on Intel platforms.

Committer testing:

  root@x1:~# perf test tpebs
  123: test Intel TPEBS counting mode                                  : Ok
  root@x1:~# set -o vi
  root@x1:~# perf test tpebs
  123: test Intel TPEBS counting mode                                  : Ok
  root@x1:~# perf test -v tpebs
  123: test Intel TPEBS counting mode                                  : Ok
  root@x1:~# perf test -vvv tpebs
  123: test Intel TPEBS counting mode:
  --- start ---
  test child forked, pid 16603
  Testing without --record-tpebs
  Testing with --record-tpebs
