perf test: Fix test case perf evlist tests for s390x
[ 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.
Output before:
# ./perf test 78
78: perf evlist tests : FAILED!
#
Output after:
# ./perf test 78
78: perf evlist tests : Ok
#
Fixes: db452961de939225 ("perf tests evlist: Add basic evlist test")
