perf test: Fix test perf evlist for z/VM s390x
[ 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
#
Fixes: b04d2b9199129f4f ("perf test: Fix test case perf evlist tests for s390x")
