perf tests: Give a bit more information on the CQM test failure path 

Before:

  $ perf test -v cqm
  48: Test intel cqm nmi context read                          :
  --- start ---
  test child forked, pid 1681
  parse_events failed
  test child finished with -2
  ---- end ----
  Test intel cqm nmi context read: Skip
  $

After:

  $ perf test -v cqm
  48: Test intel cqm nmi context read                          :
  --- start ---
  test child forked, pid 1681
  parse_events failed, is "intel_cqm/llc_occupancy/" available?
  test child finished with -2
  ---- end ----
  Test intel cqm nmi context read: Skip
