Subject: [PATCH] torchPackages, torch-repl: remove

See https://github.com/NixOS/nixpkgs/issues/71888
and https://github.com/NixOS/nixpkgs/issues/56398

To sump up, development has moved on to other technologies than lua:
https://github.com/torch/torch7#development-status
and the current packages are broken anyway.
