node: --no-browser-globals configure flag

Introduce `--no-browser-globals` configure flag. With this flag set, following
globals won't be exported:

- `setTimeout`, `clearTimeout`, `setInterval`, `clearInterval`,
  `setImmediate`, `clearImmediate`
- `console`

These are provided by the DOM implementation in browser, so the
`--no-browser-globals` flag may be helpful when embedding node.js within
chromium/webkit.
