22 hoursutil/nvmutil: rand: use getrandom on newer linuxLeah Rowe
we still fall back to the old /dev/urandom read on older linux, via runtime detection (ENOSYS). getrandom is better, because it guarantees entropy via blocking, and works even when /dev/urandom is unavailable. it has the same practical benefit as arc4random, which i use on bsd. linux can have arc4random, but not every linux libc has it, so it's better to use getrandom on linux. older linux will fall back to /dev/urandom Signed-off-by: Leah Rowe <leah@libreboot.org>
