runtime: Correct permissions error in unit tests
runtime: Correct permissions error in unit tests

The tests for watching files would fail if the parent directory of
the tests tmp files was unable to have a watch initialized on it.

To keep everything inside the temp filesystem tree this pushes the
test files down one directory and buffers with a "test" parent dir.
