Subject: [PATCH] Fail the build if clippy tests don't pass

This was removed in
https://github.com/rust-lang/rust/pull/113260/commits/de69d556eb5006a21f868b8c12d48f0ef1308a5a#diff-8479eab02701e686aedb15b567dc8fc31220c6e4efb9565ccc9d662b7fee2214
which caused CI to ignore clippy failures. This adds back the exit,
which should cause CI to fail again if a test is broken (like right
now, as clippy tests are broken on master).
