perf test: Add perf_event_attr test for record dummy event

If only dummy event is recorded, tracking event is not needed.
Add this test scenario.

Test result:

  # ./perf test list 2>&1 | grep 'Setup struct perf_event_attr'
   17: Setup struct perf_event_attr
  # ./perf test 17 -v
   17: Setup struct perf_event_attr                                    :
  --- start ---
  test child forked, pid 720198
  <SNIP>
