perf test: Fix 'perf script' tests on s390

Browse source 
In linux next repo, test case 'perf script tests' fails on s390.

The root case is a command line invocation of 'perf record' with
call-graph information. On s390 only DWARF formatted call-graphs are
supported and only on software events.

Change the command line parameters for s390.

Output before:

  # perf test 89
  89: perf script tests              : FAILED!
  #

Output after:

  # perf test 89
  89: perf script tests              : Ok
  #
