Subject: [PATCH v7 0/6] 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 v6:
- Fixed the typos.

This patch series is based on 'next' branch of linux-kselftest.
Note that Patch [4/6] uses KHDR_INCLUDES which is introduced by a patch
on 'next' branch of linux-kselftest (not merged in mainline yet)
