upstream-updater: Rename record field.

The next commits will make the functions, which are currently importing the
latest version of a package, change into importing the latest or a given
version of the package (for those updaters supporting specifying a version).
Thus the name ‘latest‘ is no longer appropriate.

* guix/upstream.scm (upstream-updater) Rename field [latest] to
  [import]. (lookup-updater, package-latest-release) Adjust fieldname
  accordingly.
