`clippy-driver` no longer builds after rust-lang/rust#68133

[rust-highfive]

Hello, this is your friendly neighborhood mergebot.
After merging PR #68133, I observed that the tool clippy-driver no longer builds.
A follow-up PR to the repository https://github.com/rust-lang/rust-clippy is needed to fix the fallout.

cc @Centril, do you think you would have time to do the follow-up work?
If so, that would be great!

cc @petrochenkov, the PR reviewer, and nominating for compiler team prioritization.
