import: gnu: Update to the (guix upstream) API.

This is a followup to 0a7c5a0.

* guix/import/gnu.scm (preferred-archive-type): Use
  'upstream-source-archive-types' instead of 'gnu-release-archive-types'.
  (gnu-package->sexp): Use 'upstream-source-urls' et al.  Update call to
  'download-tarball'.
  (gnu->guix-package): Use <upstream-source> instead of <gnu-release>.
* guix/upstream.scm (upstream-source-archive-types): Export.
