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
#
