Docker setup for privoxy-blocklist & Privoxy

[Andrwe]

In this commit @mikemucc has implemented a Docker setup that runs Privoxy and privoxy-blocklist.

This is a nice approach for running Privoxy on any system supporting Docker and using Adblock lists.

With this issue the following topics should be investigated:

• create Dockerfile to generate container running Privoxy and privoxy-blocklist
• build & provide Docker image via a Docker registry on every new version and snapshot on every pull request
• create configuration for LXC based containers to support e.g. Turris devices natively running LXC based container implementation
• check CPU architectures that can be supported (e.g. x86, ARM)

For what it's worth, I've created an image that uses your script: https://github.com/Tardo/docker-privoxy-https

** I have modified your script a bit to make it work without requiring root.

@Tardo thank you very much for this hint. I'll check your project when I start working on this idea.

Building the container for ARM64 should be as simple as passing --platform linux/arm64 to the docker build command.
