For example the ftrace tests take multiple minutes to run, so they were given longer in commit b43e78f65b1d ("tracing/selftests: Turn off timeout setting"). This works when the tests are run from the source tree. However if the tests are installed with "make -C tools/testing/selftests install", the settings files are not copied into the install directory. When the tests are then run from the install directory the longer timeouts are not applied and the tests timeout incorrectly. So add the settings files to TEST_FILES of the appropriate Makefiles to cause the settings files to be installed using the existing install logic.
