perf test: Fix test 21 for s390x
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.
