[PATCH v2 22/27] perf tests: Support 'Track with sched_switch' test for hybrid

[Jin Yao]

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.

root@otcpl-adl-s-2:~# ./perf test 35
35: Track with sched_switch                                         : Ok
