Include some trivial sandboxing options in the provided service files
as an example and lead users to `systemd-analyze security`.
While being a trivial change and far from a secure service it is an
improvement and may push downstream packagers and/or users to add even
a bit of sandboxing.

While these unit files were good for a user install, they were not
appropriate for running *system* services. Since most users nowadays
use `rad node` to manage their node, it makes more sense for the unit
files to be oriented towards server use.
