server: Use Dockerfile and build script instead of godockerize

Created by: keegancsmith

This is a replacement which is using the same Dockerfile godockerize generates, as well as the same build commands. It isn't that nice, but is a good starting point for improving the Dockerfile.

Using the same techniques we can remove godockerize for all targets. I have more changes to clean this up so its more "normal", but I realised I should of sent this out sooner so did that now.
