perf test: Update "sample parsing" test for PERF_SAMPLE_TRANSACTION

In fact the "sample parsing" test does not automatically check new
sample type bits - they must be added to the comparison logic.

Doing that shows that the test fails because the functions
perf_event__synthesize_sample() and perf_event__sample_event_size() have
not been updated with PERF_SAMPLE_TRANSACTION either.
