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
