The datastore/backup debug helpers should always be available, they
can help a lot in dire times, so making them available directly via
the server package (alongside the manager CLI tool) is nicer for the
user.
Additionally, building a package can be quite time consuming in this
repo, as some tools like dwarves and other debug symbol stuff has to
scan the quite big rust binaries. So dropping a binary package shaves
of a noticeable bit of build time too.
