treewide: skip generating shell completions using $out/bin/… when cross compiling

This focuses on Rust packages, since the most commonly used argument parser library (clap/structopt) makes the following pattern natural and thus common: postInstall = '' installShellCompletion --cmd foo \ --bash <($out/bin/foo completion bash) \ … This commit just guards those with lib.optionalString (stdenv.buildPlatform.canExecute stdenv.hostPlatform) splitting the string where unrelated actions are performed.
