Subject: [PATCH] cups-kyocera-3500-4500: fix broken download URL

Kyocera seem to have removed the previous download location, and
repackaged their drivers elsewhere, including re-gzipping the previous
package.  Update the download URL, and rewrite the download mechanism to
handle the double-compressed archive.

The new unpack code is largely adapted from the fetchzip code.

Also add a Wayback Machine URL as an alternative source to reduce the
chances the package will break if Kyocera change their URLs again.
