Subject: [PATCH] Propagate Google API keys into the chroot.

These are a new type of credential baked into chrome/chromium for
developers without internal copies of ChromeOS, and not building internal
versions of Chrome.

We automatically move .googleapikeys into the chroot each time.

We don't overwrite the destination, so that people can configure keys the
way they want. If they just don't want to be bothered, the best thing happens
the easiest way.  Get Keys, put them in home.  Keep working.
