examples/rust: Use `CARGO_CFG_TARGET_ARCH` environment variable #261

As per #257, it appears as if std::env::consts::ARCH does not get updated to the target architecture in a cross-compilation context. Switch to using the CARGO_CFG_TARGET_ARCH environment variable in the hopes that we get the desired behavior.

Great, thanks for fixing!
