[PATCH v2 24/27] perf tests: Support 'Session topology' test for hybrid

[Jin Yao]

Force to create one event "cpu_core/cycles/" by default,
otherwise in evlist__valid_sample_type, the checking of
'if (evlist->core.nr_entries == 1)' would be failed.

41: Session topology                                                : Ok
