Subject: [PATCH v2 21/27] perf tests: Skip 'Setup struct perf_event_attr' test for hybrid

For hybrid, kernel introduces new perf type PERF_TYPE_HARDWARE_PMU (6)
and it's assigned to hybrid hardware events.

    matching [event:base-stat]
      to [event-6-17179869184-4]

      [type] 0 6
    ->FAIL
    match: [event:base-stat] matches []
    event:base-stat does not match, but is optional

expected type=6, got 0
expected config=17179869184, got 0
FAILED './tests/attr/test-stat-C0' - match failure

The type matching is failed because one type is 0 but the
type of hybrid hardware event is 6. We temporarily skip this
test case and TODO in future.
