Thomas Richter 6f8a0b0952 perf test: Fix test 21 for s390x 
[ Upstream commit 996548499d ]

Test case 21 (Number of exit events of a simple workload) fails on
s390x. The reason is the invalid sample frequency supplied for this
test. On s390x the minimum sample frequency is much higher (see output
of /proc/service_levels).

Supply a save sample frequency value for s390x to fix this.  The value
will be adjusted by the s390x CPUMF frequency convertion function to a
value well below the sysctl kernel.perf_event_max_sample_rate value.
