Subject: [PATCH v2 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 Makefile of resctrl_test and Makefile of selftest, to
  build/run resctrl_tests by using kselftest framework.
- I set the limited time for resctrl_tests to 120 seconds, to ensure the
  resctrl_tests finish in limited time.
- When resctrl file system is not supported or resctrl_tests is not run
  as root, return skip code of kselftest.
- If it is not finish in limited time, terminate resctrl_tests same as
  executing ctrl+c.

Difference from v1:
- I change the order of patches according to Reinette's review.
- "LDLIBS + = -lnuma" has no dependencies on this patch series, delete
  it from [PATCH v2 2/5].
- I separate the license info of Makefile into a new patch [PATCH v2
  3/5].
- I separate "limited time" into a new patch [PATCH v2 4/5].
(There is no change in [PATCH v2 1/5] and [PATCH v2 5/5])
In addition, I think 120s is not a problem since some tests have longer
timeout (e.g. net test is 300s), please let me know if this is wrong

Thanks,
