[ Upstream commit 008603bda19b29687edce533e4c09acff68c1077 ]
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

[ Upstream commit b04d2b9199129f4f0c992a518c0fb78c2efc1064 ]
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.
