Eliminate uses of `config.cudaSupport or false` and alike, since the
option is now declared in config.nix with a default value
fd .nix -t f -x sed 's/config\.cudaSupport or false, cudaPackages [?] [{][}]/config.cudaSupport, cudaPackages ? { }/' '{}' -i
fd .nix -t f -x sed 's/config\.cudaSupport or false/config.cudaSupport/' '{}' -i
fd .nix -t f -x sed 's/cudaSupport = pkgs.config.cudaSupport/inherit (pkgs.config) cudaSupport/' '{}' -i
fd .nix -t f -x sed 's/cudaSupport = config.cudaSupport/inherit (config) cudaSupport/' '{}' -i
