[PATCH v5 21/26] perf tests: Support 'Track with sched_switch' test for hybrid

Since for "cycles:u' on hybrid platform, it creates two "cycles".
So the number of events in evlist is not expected in next test
steps. Now we just use one event "cpu_core/cycles:u/" for hybrid.

# ./perf test 35
35: Track with sched_switch : Ok

v5:
- Drop the variable 'hybrid' and use 'if (perf_pmu__has_hybrid())'
directly.
