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 v4:
- Add comment for settings file. [PATCH v5 2/6]
- Improved README of resctrl_tests and rewirte changelog. [PATCH v5 5/6]
