Limited the API surface of the UpdateCheckService

refs https://github.com/TryGhost/Team/issues/728

- This is continuation of the previous commit. TLDR: Passing only the necessary API endpoint function makes it easier to reason about what dependencies the UpdateCheckService has to deal with
- Limited urlUtils to only one function as that's all the UpdateCheck uses. Next step will be removing the function completely as and passing a 'blogURL' as a config value (way better readability this way)
