Ian Wienand 67ae84ce39 ensure-rust: rework global install ... I think the secondary "rustup default" was intended to make sure the Zuul user sets up to use the installed rust toolchain (I32f9b285904a7036f9a80ada8a49fa9cf31b5163) but actually results in a re-download of components and another local installation. This isn't really the intention, and also doubles the time spent installing. From the linked comment, it seems like we're not doing our global install correctly; even putting it in /usr doesn't avoid the need for RUST_HOME to be set. Take it's suggestion and install out-of-the-way in /opt, use a small /usr/local/bin wrapper to call with correct env vars set and then setup the installed global binary names to be called via that.
