perf tests: Add framework for automated perf_event_attr tests
The idea is run perf session with kidnapping sys_perf_event_open
function. For each sys_perf_event_open call we store the perf_event_attr
data to the file to be checked later against what we expect.
You can run this by:
$ python ./tests/attr.py -d ./tests/attr/ -p ./perf -v
v2 changes:
- preserve errno value in the hook
