Indicate environment in container hostnames

While it is a tiny change, it does help to have an explicit indication
of what container you are currently working with, especially when you
need to do specific tasks inside the container itself with something
like `nsenter …` or `guix container exec …`.

With this commit, instead of a generic prompt like:

    `root@genenetwork /#`,

you get a more specific prompt such as

    `root@genenetwork-production /#`

which goes some ways in avoiding mistakes.
