perf test: Fix test case 81 ("perf record tests") on s390x

perf test -F 81 ("perf record tests") -v fails on s390x on the
linux-next branch.

The test case is x86 specific can not be executed on s390x.  The test
case depends on x86 register names such as:

  ... | egrep -q 'available registers: AX BX CX DX ....'

Skip this test case on s390x.

Output before:

  # perf test -F 81
  81: perf record tests                       : FAILED!
  #

Output after:

  # perf test -F 81
  81: perf record tests                       : Skip
  #
