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

Perf test case 78: perf evlist tests fails on s390.
The failure is causes by grouping events cycles and instructions because
sampling does only support event cycles. Change the group to software
events to fix this.
Output before:
# ./perf test 78
78: perf evlist tests : FAILED!
#
Output after:
# ./perf test 78
78: perf evlist tests : Ok
