getconf: remove workaround for old NDKs.
macOS remains awkward, though, but this retains our Android/Linux behavior and is closer to the platform's getconf(1) for macOS. Strictly macOS denies all knowledge of UIO_MAXIOV, but the "undefined" you'll get from this patch seems closer than the "1024" we used to give.
