This renames wasm32-unknown-wasi to wasm32-wasi, omitting the vendor component. This follows aarch64-linux-android, x86_64-fuchsia, and others in omitting the vendor field, which has the advantage of aligning with the [multiarch tuple](https://wiki.debian.org/Multiarch/Tuples), and of being less noisy.
