The new V8 seems to be optimizing the functions we use in this test
faster than before. Increasing the sampling frequency for Linux perf
fixes the issue.

The V8 7.3 update requires the following adjustments to the
postmortem debugging metadata constants:
- v8dbg_prop_idx_first was removed in
1ad0cd560e
- v8dbg_jsarray_buffer_was_neutered_mask was renamed to
v8dbg_jsarray_buffer_was_detached_mask in
f68ee6e7e4
- v8dbg_jsarray_buffer_was_neutered_shift was renamed to
v8dbg_jsarray_buffer_was_detached_shift in
f68ee6e7e4
- v8dbg_class_Map__instance_descriptors__DescriptorArray moved to
v8dbg_class_Map__raw_instance_descriptors__DescriptorArray and
began using ACCESSORS2 in
799dfad502
The following postmortem debugging constants were also impacted
by V8's introduction of ACCESSORS2, but do not need to be updated
the test:
- v8dbg_class_ThinString__actual__String changed in
0f581e4b99
- v8dbg_class_UncompiledData__inferred_name__String changed in
0f581e4b99
- v8dbg_class_JSFunction__shared__SharedFunctionInfo changed in
81620900e9
- v8dbg_class_SharedFunctionInfo__function_data__Object had its
accessor removed in
a55803a15d
This has been fixed in gen-postmortem-metadata.py.

This commit adds a test to validate if Linux perf is working correctly
on Node.js. The test is marked as flaky because its intention is to let
us know when changes on V8 potentially broke Linux perf, so we can fix
it before a new version of V8 lands on Node.js master.
