[PATCH v2 25/27] perf tests: Support 'Convert perf time to TSC' test for hybrid

[Jin Yao]

Since for "cycles:u' on hybrid platform, it creates two "cycles".
So the second evsel in evlist also needs initialization.

With this patch,

root@otcpl-adl-s-2:~# ./perf test 71
71: Convert perf time to TSC                                        : Ok
