[PATCH] perf test: Fix test case 81 on s390x

[Thomas Richter <tmricht@linux.ibm.com>]

perf test -F 81 -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
 #
