Thomas Richter 5bb017d4b9 perf test: Fix error message for test case 71 on s390, where it is not supported 
Test case 71 'Convert perf time to TSC' is not supported on s390.

Subtest 71.1 is skipped with the correct message, but subtest 71.2 is
not skipped and fails.

The root cause is function evlist__open() called from
test__perf_time_to_tsc().  evlist__open() returns -ENOENT because the
event cycles:u is not supported by the selected PMU, for example
platform s390 on z/VM or an x86_64 virtual machine.

The PMU driver returns -ENOENT in this case. This error is leads to the
failure.

Fix this by returning TEST_SKIP on -ENOENT.

Output before:
 71: Convert perf time to TSC:
 71.1: TSC support:             Skip (This architecture does not support)
 71.2: Perf time to TSC:        FAILED!

Output after:
 71: Convert perf time to TSC:
 71.1: TSC support:             Skip (This architecture does not support)
 71.2: Perf time to TSC:        Skip (perf_read_tsc_conversion is not supported)

This also happens on an x86_64 virtual machine:
   # uname -m
   x86_64
   $ ./perf test -F 71
    71: Convert perf time to TSC  :
    71.1: TSC support             : Ok
    71.2: Perf time to TSC        : FAILED!
   $

Committer testing:

Continues to work on x86_64:

  $ perf test 71
   71: Convert perf time to TSC    :
   71.1: TSC support               : Ok
   71.2: Perf time to TSC          : Ok
  $
