Title: Redirect legacy traffic to legacy.polyfill.io

In preparation for moving the service to the polyfill.io domain:

```
> curl -i -H 'Referer: http://www.manrepeller.com/' -H 'Host: polyfill.io' -H 'User-Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_0) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/38.0.2125.111 Safari/537.36' http://localhost:3000/normalize.css

The hostname www.manrepeller.com is known to be a user of the previous version of polyfill.io, so for backwards compatibility we're redirecting you to legacy.polyfill.io which will handle your request using the old version of the service. The legacy version will be discontinued in the future, so please update to the new version, and then let us know by raising an issue in our repo at https://github.com/financial-times/polyfill-service.⏎
