Subject: [PATCH v3 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.
# ./perf test 17 -vvv

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.
