Working version for ubuntu 14.04

Came across this project while looking for a Docker varnish container. 

I was not able to get the official docker hub build working, so attempted a local build. That was also failing with errors about libc6 dependancies. I stripped down the Dockerfile a bit and was able to get it building and working.

I am not sure if you still want the locales package. I left it out of this set of commits.
