Rich Trott 7487d61981 test: refactor test-fs-readfile-unlink
* Use tmp directory instead of mutating the fixtures directory.
* Add comment explaining that the unlinkSync() at the end of the test is
  part of the test. Otherwise it may be tempting to remove it as
  unnecessary tmp directory cleanup.
