Subject: [PATCH] Add Zsh completion for target triples

Target triples are used for specifying targets for e.g. `cargo build
--target thumbv7em-none-eabihf` where `thumbv7em-none-eabihf` is the
target triplet.
For more information on target triples, see
<https://doc.rust-lang.org/cargo/appendix/glossary.html#target>.
