Arnaldo Carvalho de Melo e9c08f7229 perf test sigtrap: Print errno string when failing 
Helps a bit the user figuring out why it is failing:

Before:

  $ perf test sigtrap
  73: Sigtrap                                                         : FAILED!
  $ perf test -v sigtrap
  73: Sigtrap                                                         :
  --- start ---
  test child forked, pid 3816772
  FAILED sys_perf_event_open()
  test child finished with -1
  ---- end ----
  Sigtrap: FAILED!
  $

After:

  $ perf test sigtrap
  73: Sigtrap                                                         : FAILED!
  $ perf test -v sigtrap
  73: Sigtrap                                                         :
  --- start ---
  test child forked, pid 3816772
  FAILED sys_perf_event_open(): Permission denied
  test child finished with -1
  ---- end ----
  Sigtrap: FAILED!
