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.
* guix/scripts/substitute.scm (lookup-narinfo): Cache connection by using
open-connection-for-uri/cached.
