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.
Fixes: 7248e308a575 ("perf tools: Record ARM64 LR register automatically")

Hi,
Friendly ping on this perf-test fix for arm64
I will include some quick test notes:
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'
[...]
Thanks,
German
