Allow some more tests to run in instances. There's a few tests that
require something in README to be present to run. But currently README
can't be used for instance tests. Fix that and then allow 4 more tests
to run in instances.

      selftests/tracing: Test only toplevel README file not the instances
      selftests/ftrace: Clean up triggers after setting them
      selftests/tracing: Allow some more tests to run in instances
