[PATCH] perf test: Skip perf data type profiling tests for s390

[Thomas Richter]

Test case 'perf data type profiling tests' fails on s390 with this
error:

  # ./perf mem record -- ./perf test -w code_with_type
  failed: no PMU supports the memory events
  # echo $?
  255
  #

because s390 does not support memory events at all. According to the
man page, perf annotate --code-with-type only works with memory
instructions only.  As command 'perf mem record ...' is not supported
on s390, skip this test for s390.

Output before:
 # ./perf test 'perf data type profiling tests'
 77: perf data type profiling tests                        : FAILED!

Output after:
 # ./perf test 'perf data type profiling tests'
 77: perf data type profiling tests                        : Skip
