[PATCH] perf/test: Fix wrong size for perf test Setup struct perf_event_attr

[Thomas Richter <tmricht@linux.ibm.com>]

The test case ./perf test 'Setup struct perf_event_attr' fails.
On s390 this output is observed:

 # ./perf test -Fvvvv 17

    ->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
