Subject: [PATCH v3 5/7] perf test: Update base-record & system-wide-dummy attr expected values for test-record-C0

1. Because a dummy sideband event is added to the sampling of specified
   CPUs. When evlist contains evsel of different sample_type,
   evlist__config() will change the default PERF_SAMPLE_ID bit to
   PERF_SAMPLE_IDENTIFICATION bit.
   The attr sample_type expected value of base-record and system-wide-dummy
   in test-record-C0 needs to be updated.

2. The perf record uses evlist__add_aux_dummy() instead of
   evlist__add_dummy() to add a dummy event.
   The expected value of system-wide-dummy attr needs to be updated.

The perf test result is as follows:

  # ./perf test list  2>&1 | grep 'Setup struct perf_event_attr'
   17: Setup struct perf_event_attr
  # ./perf test 17
   17: Setup struct perf_event_attr                                    : Ok
