Docker security

[m-1-k-3]

With the pull request from @Anemosx we now have full Docker support in emba.

As discussed here #66 (comment) this also includes new security issues. Nevertheless we see a massive improvement compared to running emba on your host.

Let's use this Issue to discuss further steps.

As far as I can see all of our security issues are based on the fact that we currently need the docker images from fact-extractor and cwe-checker. So, if we install them locally on our Docker image or on our Kali host with our installer we do not need to expose the following critical files/directories:
- /var/run/docker.sock:/var/run/docker.sock
- /tmp/:/tmp/
As far as I can see we could close this issue with local install of the mentioned tools.
