freebsd-update(8) without an echo of "You must be root to run this."

[Graham Perrin]

<https://cgit.freebsd.org/src/tree/usr.sbin/freebsd-update/freebsd-update.sh?id=48ffe56ac5b7adb5b851d32be12b2ec0f13705a4#n555>

         echo "You must be root to run this."

Below: is this my PEBKAM, or (with a system that is preconfigured to 
deny login as root) _should_ there be an echo of the requirement to run 
as root?

Does this look reasonable (y/n)?
