Remove an unchecked_claim_error_was_emitted
call.
When `catch_fatal_errors` catches a `FatalErrorMarker`, it returns an `ErrorGuaranteed` that is conjured out of thin air with `unchecked_claim_error_was_emitted`. But that `ErrorGuaranteed` is never used. This commit changes it to instead conjure a `FatalError` out of thin air. (A non-deprecated action!) This makes more sense because `FatalError` and `FatalErrorMarker` are a natural pairing -- a `FatalErrorMarker` is created by calling `FatalError::raise`, so this is effectively getting back the original `FatalError`. This requires a tiny change in `catch_with_exit_code`. The old result of the `catch_fatal_errors` call there was `Result<Result<(), ErrorGuaranteed>, ErrorGuaranteed>` which could be `flatten`ed into `Result<(), ErrorGuaranteed>`. The new result of the `catch_fatal_errors` calls is `Result<Result<(), ErrorGuaranteed>, FatalError>`, which can't be `flatten`ed but is still easily matched for the success case.
