nixos/atd: remove "batch" from setuid wrappers 

"batch" is a shell script so invoking it via setuid wrapper never worked
anyway. (The kernel drops perms on executables with shebang.) A previous
nixpkgs commit made "batch" invoke the NixOS setuid "at" wrapper to gain
needed privileges.

Thanks to @yesbox for noticing.
