scripts: substitute: Cache connection when looking for narinfos.

The process-substitution procedure is opening two distinct connections. The
first one when looking for narinfo by calling lookup-narinfo and the other one
when fetching nar files.

Cache the connection when looking for narinfos so that process-substitution
only opens one connection.

open-connection-for-uri/cached.
