perf tests: Fix attr tests size values to cope with machine state on interrupt ABI changes

Following change adjusted 'struct perf_event_attr', but let
the attr test's sizes untouched:
  60e2364e perf: Add ability to sample machine state on interrupt

  [jolsa@krava perf]$ ./perf test attr -vv
  --- start ---
  test child forked, pid 9719
  running './tests/attr/test-stat-group1'
    'PERF_TEST_ATTR=/tmp/tmp4drvul ./perf stat -o /tmp/tmp4drvul/perf.data -e '{cycles,instructions}' kill >/dev/null 2>&1' ret 1
  expected size=96, got 104
  FAILED './tests/attr/test-stat-group1' - match failure

Adjusting test size values for attr test.
