Add proto Dockerfile

[mattjtodd]

Hi, I'm quite interested in the work being done to take POP11 into the x64 world!

I've created a sample Dockerfile, which seems to work based on my shaky knowledge of POP11.

If you've not encountered it before, Docker is a container image builder and runtime for packaging up apps much like POP11 to make them much more portable.

https://www.docker.com/

There are some errors generated during the build which I don't seem to be able to resolve, but I can run the corepop process to run pop command in the REPL or with files.

@hebisch I'd be interested in working out how this should be build and packaged to make it easier for others to run in a container correctly (if it's not correct now).

I containerised the old 32 bit version as well, you can see this here - https://github.com/mattjtodd/docker-poplog

Thanks for your work. Currently Poplog build process is rather messy, that is why build scripts are not in
the repository -- I would like to keep repository clean. For the same reason I prefer that ATM dockerfile
is outside (in pull request).

@mattjtodd I realize this is an ancient request, but I have some forks going on that I could try this out. I think the interesting packaging is actually with nix and not docker, but I am willing to have a look at this. I have some downstream ports going.

Nice, let me know if you have any questions.
