    build: Add `make clippy` option for Rust linting.
    
    Note that clippy is quite loud/obnoxious, as its name would imply.
    This target isn't meant to run on CI, or even necessarily exit
    cleanly.  It's merely a way for developers to check if they've made
    any glaring mistakes, or done awkward things they might not have
    otherwise realised.  We *can* configure it to be quieter in the
    future, but it's probably not worth rabbitholing on.
    
     * CLOSES #22156: https://bugs.torproject.org/22156
