perf test: Fix arm64 perf_event_attr tests wrt --call-graph initialization

The struct perf_event_attr is initialised differently in Arm64 when
recording in call-graph fp mode, so update the relevant tests, and add
two extra arm64-only tests.

Before:

  $ perf test 17 -v
  17: Setup struct perf_event_attr
  [...]
  running './tests/attr/test-record-graph-default'
  expected sample_type=295, got 4391
  expected sample_regs_user=0, got 1073741824
  FAILED './tests/attr/test-record-graph-default' - match failure
  test child finished with -1
  ---- end ----

After:

[...]
  running './tests/attr/test-record-graph-default-aarch64'
  test limitation 'aarch64'
  running './tests/attr/test-record-graph-fp-aarch64'
  test limitation 'aarch64'
  running './tests/attr/test-record-graph-default'
  test limitation '!aarch64'
  excluded architecture list ['aarch64']
  skipped [aarch64] './tests/attr/test-record-graph-default'
  running './tests/attr/test-record-graph-fp'
  test limitation '!aarch64'
  excluded architecture list ['aarch64']
  skipped [aarch64] './tests/attr/test-record-graph-fp'
[...]
