substitute-binary: Store the cache's URI in the local cached narinfo.
* guix/scripts/substitute-binary.scm (<narinfo>)[uri-base]: New field. (narinfo-maker): Pass CACHE-URL as the 'uri-base' value. (string->narinfo): Add 'cache-uri' parameter. (lookup-narinfo)[cache-entry]: Switch to version 1. Add 'cache-uri' field. Adjust body accordingly. (remove-expired-cached-narinfos): Switch to version 1 by default.
