cvs-download: Add guile-json and gnutls extensions.

This partially fixes: <https://issues.guix.gnu.org/48152>.

The (guix build download-nar) module drags the (guix build download) module
that autoloads (guix swh).

[13/26] Loading './guix/swh.scm'...
;;; Failed to autoload swh-download-directory in (guix swh):
;;; no code for module (json)
