A few cleanups in test262.status

A few cleanups in test262.status

- Removed PASS/FAIL line for arrow/rest params test which should now pass.
- Moved soon-to-be-changed tests about built-in prototypes as plain objects
  to INVALID section (and noted that they'll be fixed with the
  next test262 roll).
