This adds a Make include file which most selftests can then include to get the run_tests logic. On its own this has the advantage of some reduction in repetition, and also means the pass/fail message is defined in fewer places. However the key advantage is it will allow us to implement install very simply in a subsequent patch. The default implementation just executes each program in $(TEST_PROGS). We use a variable to hold the default implementation of $(RUN_TESTS) because that gives us a clean way to override it if necessary, ie. using override. The mount, memory-hotplug and mqueue tests use that to provide a different implementation. Tests are not run via /bin/bash, so if they are scripts they must be executable, we add a+x to several.
