Binary package hint: ubiquity

sabdfl has requested that we either remove the update installer link from the first page of ubiquity, or only show it when a critical update is available. Please allow a freeze exception for the following patch, which implements this functionality.

It has been suggested by Colin that we host the update hint file on changelogs.ubuntu.com, but if the release team thinks there's a better place for it, I'm open to suggestions.

The code itself is quite small and simplistic, with the only complexity rising from the need to avoid superfluous calls to wget.
