Subject: [PATCH] daemon: Run 'guix perform-download' directly.

* nix/scripts/download.in: Remove.
* nix/local.mk (nodist_pkglibexec_SCRIPTS): Remove 'scripts/download'.
* config-daemon.ac: Don't output 'nix/scripts/download'.
* nix/libstore/builtins.cc (builtinDownload): Invoke 'guix
perform-download' directly.
