Arnaldo Carvalho de Melo 239849dde3 perf tests: No need to set attr.sample_freq for tracking !PERF_RECORD_SAMPLE 
We were asking for a 4kHz sample_freq, making the test fail needlessly
when the system reduced /proc/sys/kernel/perf_event_max_sample_rate
below that.

Before:

  # perf test -vv dummy
  23: Test using a dummy software event to keep tracking       :
  --- start ---
  test child forked, pid 32421
  ------------------------------------------------------------
  perf_event_attr:
    type                             1
    size                             112
    config                           0x9
    { sample_period, sample_freq }   4000
    sample_type                      IP|TID|ID|PERIOD
  <SNIP>
  sys_perf_event_open failed, error -22
  Unable to open dummy and cycles event
  test child finished with -2
  ---- end ----
  Test using a dummy software event to keep tracking: Skip
  #
  [root@zoo ~]# cat /proc/sys/kernel/perf_event_max_sample_rate
  1000

After:

  [root@zoo ~]# perf test dummy
  23: Test using a dummy software event to keep tracking       : Ok
