rust: updated to 1.41.1

What's in 1.41.1 stable
Rust 1.41.1 addresses two critical regressions introduced in Rust 1.41.0: a soundness hole related to static lifetimes, and a miscompilation causing segfaults. These regressions do not affect earlier releases of Rust, and we recommend users of Rust 1.41.0 to upgrade as soon as possible. Another issue related to interactions between 'static and Copy implementations, dating back to Rust 1.0, was also addressed by this release.
