rust-dependencies: switch from `users` to `whoami`
`users` is unmaintained, with the maintainer apparently MIA. `whoami` is a
popular crate that does simple wrapping of platform-specific calls.
This makes the overhead from using `blackbox` lower. It used to be up 10ms
on slower hardware for both calls, now down to <1ms which is always good.
