[REQUEST] docker for arm64

[dony71]

Notice docker only for amd64 architecture
Is it possible to make docker for arm64?

I'm moving this over to the docker-mycroft repo. There are ongoing discussions there for armhf as well.

So, I didn't realize there was no support for this. I just updated my saltstack, found that some necessary docker features aren't supported in the docker-formula, spent hours updating their code, submitted PRs, and then I find this just now haha...

I don't know if this worked or not in the past but today I just changed the Dockerfile first line:

alvaro@silvia:~/docker-mycroft $ diff Dockerfile arm64v8.Dockerfile 
1c1
< FROM ubuntu:18.04
---
> FROM arm64v8/ubuntu:18.04

And seems like everything is working fine.
