[Packaging] Move user out of systemd files and add to tarball

With the `deluge` user specified in the unit files it ties it to
that user and makes it unavailable for re-use by systemd user instance.

Remove the user and group from the unit files and put them in a separate
`user.conf` file that should be installed as an override file e.g. for
deluged.service this would be placed as follows:

    /etc/systemd/service/deluge.service.d/user.conf

Add the systemd files to the tarball for package maintainers.

Closes: #2034
