[PATCH v3 0/5] selftests/resctrl: Add resctrl_tests into kselftest set

Hello,

The aim of this series is to make resctrl_tests run by using
kselftest framework.
- I modify resctrl_test Makefile and kselftest Makefile,
to enable build/run resctrl_tests by using kselftest framework.
Of course, users can also build/run resctrl_tests without
using framework as before.
- I change the default limited time for resctrl_tests to 120 seconds, to
ensure the resctrl_tests finish in limited time on different environments.
- When resctrl file system is not supported by environment or
resctrl_tests is not run as root, return skip code of kselftest framework.
- If resctrl_tests does not finish in limited time, terminate it as
same as executing ctrl+c that kills parent process and child process.

Difference from v2:
- I reworte changelog of this patch series.
- I added how to use framework to run resctrl to README. [PATCH v3 2/5]
- License has no dependencies on this patch series, I separated from it this patch series to another patch.

With regard to the limited time, I think 120s is not a problem since some tests have a longer
timeout (e.g. net test is 300s). Please let me know if this is wrong.

Thanks,
