Title: Provide debug info to recover build cache

Building Haskell apps for Heroku often takes hours and can cause timeouts when trying to upload slugs. However if I can discover the URL of the build cache Anvil creates then I can use it in my buildpack to resume and do a quick incremental build.

This pull request outputs the cache URL in the log so I can recover it if need be.
