Title: allows os-level deps

Improvement to allow os-level deps to be introduced to the container. Typical use-case for this is when you have gems in a Ruby application that require native extensions.

To utilise this functionality you just need to create a `.apt-packages` file and add packages to be installed on
separate lines.
