publish: Increase TCP buffer size when sending non-cached nars.
This increases throughput tenfold (!) on localhost when downloading large nars without '--cache'. This is a followup to 5e3d169945935b53325e6b738a307ba286751259. Reported by Maxim Cournoyer. * guix/scripts/publish.scm (http-write): In the 'application/x-nix-archive' case, add call to 'setsockopt'.
