perf test: Fix wrong size expectation for 'Setup struct perf_event_attr'

The test case "perf test 'Setup struct perf_event_attr'" is failing.

On s390 this output is observed:

 # ./perf test -Fvvvv 17
 17: Setup struct perf_event_attr                                    :

    ->FAIL
    match: [event-0-0-4] matches []
  expected size=136, got 128
  FAILED './tests/attr/test-stat-C0' - match failure

This mismatch is caused by
commit 09519ec3b19e ("perf: Add perf_event_attr::config3")
which enlarges the structure perf_event_attr by 8 bytes.

Fix this by adjusting the expected value of size.

Output after:
 # ./perf test -Fvvvv 17
