Subject: [PATCH] Add sourcemaps to entrypoint and normalise paths in the
 script (#1065)

* Add sourcemaps to entrypoint

* Make entrypoint run Draupnir relative to the script.

This is important for running draupnir from source either directly in
the directory, from ExecStart in systemd, or from inside the docker
image.

And we're making this change so that we can have better control over
the arguments we start Draupnir with in the different environments
without having to make disruptive changes.

Co-authored-by: Bea <20361868+enbea@users.noreply.github.com>

* Add changeset for source installs.

We're gonna write up a proper change log but this is just so we don't forger.
