Trigger a rebuild when `CLIPPY_CONF_DIR` changes

changelog: none

This is a fix for https://github.com/rust-lang/rust-clippy/issues/9928#issuecomment-1634698183, any time `CLIPPY_CONF_DIR` changes cargo will now rebuild the crate clippy is being run on, giving it a chance to lint with the (potentially) different config file

r? `@flip1995`
