refresh: Distinguish between "no updater" and "failing updater".

Browse source 
Previously, something like "guix refresh texmacs" would report "no
updater".  Now, it reports that the 'gnu-ftp' updater failed to list
releases.

* guix/upstream.scm (lookup-updater): Use 'find' instead of 'any' to
return the <upstream-updater>.
(package-latest-release): Adjust accordingly.
* guix/scripts/refresh.scm (check-for-package-update): When
'package-latest-release' returns #f, distinguish between "no updater"
and "failing updater".
