perf test: Fix test perf evlist for z/VM s390x

Perf test case 'perf evlist tests' fails on z/VM machines on s390.

The failure is causes by event cycles. This event is not available
on virtualized machines like z/VM on s390.

Change to software event cpu-clock to fix this.

    Output before:
      # ./perf test 78
      79: perf evlist tests              : FAILED!
      #

    Output after:
      # ./perf test 78
      79: perf evlist tests              : Ok
      #
