Subject: [PATCH 1/3] selftests/resctrl: Make resctrl_tests run using kselftest framework

From: "Tan, Shaopeng" <tan.shaopeng@...fujitsu.com>

This commit enables kselftest to be built/run in resctrl framework.
Build/run resctrl_tests by build/run all tests of kselftest, or by using
the "TARGETS" variable on the make command line to specify resctrl_tests.
To make resctrl_tests run using kselftest framework, this commit modified
the Makefile of kernel kselftest set and the Makefile of resctrl_tests.
To ensure the resctrl_tests finish in limited time, this commit changed
the default limited time(45s) to 120 seconds for resctrl_tests by adding
"setting" file.
