[PATCH v6 0/6] selftests/resctrl: Add resctrl_tests into kselftest set

[Shaopeng Tan]

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 v5:
- Changed skip message when resctrlfs is not supported. [PATCH v6 3/6]
- Changed resctrl's Makefile to always build with latest kernel headers and
  keep enabling gcc checks to detect buffer overflows. [PATCH v6 4/6]
- Made README easier to understand. [PATCH v6 5/6]
