fix: remove hardcoded HOSTNAME in Docker

Instead of hardcoding it in supervisord.conf, we simply set it to an
empty value in the Dockerfile. This prevents docker from setting it's
own value while also allowing the user to override it.

In next JS an empty HOSTNAME is equivalent to not setting it at all.
