Rick Waldron 4ea2931f16 Update all harness files to pass linting. (#1153)
```
$ python tools/lint/lint.py --whitelist lint.whitelist harness/*.js
Linting 25 files.
Linting complete. 0 errors found.
```

- Renames detachArrayBuffer-$262.detachArrayBuffer.js -> detachArrayBuffer-host-detachArrayBuffer.js (previous naming prevents command-click from terminal)
