Remove unnecessary layers in Dockerfile

[mikz]

You can take some inspiration in https://github.com/mikz/docker-plex/blob/master/Dockerfile It is significantly simpler and works like a charm.

For example your getting a deb stores it in a layer, as the remove is in another RUN command. So client will have to download it anyway.

Thanks, I didn't know each RUN incurred another download (no matter how small).
