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.
