Temporarily turn overflow checks off for rustc-rayon-core

The rustc fork of Rayon has deadlock detection code which intermittently causes overflows in the CI (see https://github.com/rust-lang/rust/issues/90227). So, as a workaround, we unconditionally turn overflow checks off for this crate only.

This workaround should be removed once #90227 is fixed.
