perf test perf-report-hierarchy: Add new test 



Super simple test to check that at least we're not segfaulting when
trying to use 'perf report --hierarchy', more subtests should be added
to make sure the output is the expected one.

This is being merged right before a fix for that that this test detects:

  # perf test hierarchy
   83: perf report --hierarchy                                         : FAILED!
  # perf test -v hierarchy
  --- start ---
