refresh: Honor user-provided target version and report downgrades.

Browse source 
Previously, 'guix refresh guile=3.0.0' would print:

  3.0.8 is already the latest version of guile

With this change, it prints:

  guile would be downgraded from 3.0.8 to 3.0.0

This is a followup to 8aeccc6240.

* guix/scripts/refresh.scm (check-for-package-update): Take an
<update-spec> instead of a <package>.  Report downgrades as such when
UPDATE-SPEC specifies a target version.
(guix-refresh): Adjust caller.
