rust: Update to 1.74.1.

pkgsrc changes:
 * remove NetBSD-8 support (embedded LLVM requires newer C++
   than what is in -8; it's conceivable that this could still
   build with an external LLVM)
 * undo powerpc 9.0 file naming tweak

Upstream changes:

Version 1.74.1 (2023-12-07)

- [Clarify guarantees for std::mem::discriminant]
