[PING PATCH v2] perf test: Fix test case perf script tests on s390

[Thomas Richter]

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 fors s390.

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

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

Fixes: 0dd5041c9a0e ("perf addr_location: Add init/exit/copy functions")
