Subject: BUILD: Simplify enabling journald on installed systems


systemd supports overrides of the standard service file to be placed in
/etc/systemd/system/<service>.service.d/

With this patch, we will install a commented-out override file to /etc
that will instruct the user on how to enable logging to journald.
