refactor: use multistage image approach to reduce size

[ZuBB]

Hello @blaise-io,

I saw that you bumped the image version recently and decided to share the changes I made some time ago finally. I managed to reduce the image size by 15Mb. I hope this change is worth including in mainline

I don't trust apteno/alpine-jq and Alpine is not supported by Acestream, can you base it on ubuntu:focal?

apteno/alpine-jq is used for downloading acestream only. Acestream still runs on top of Ubuntu (multistage build). Accordingly to dockerhub this image has been pulled 100M times. Seems like ppl have some trust in it.

Do you still wanna drop it?
