std: refactor UNIX random data generation This PR makes a number of changes to the UNIX randomness implementation: * Use `io::Error` for centralized error handling * Move the file-fallback logic out of the `getrandom`-specific module * Stop redefining the syscalls on macOS and DragonFly, they have appeared in `libc` * Add a `OnceLock` to cache the random device file descriptor
