nia 9f5312cc4e entropy: Add support for BSD sysctl(KERN_ARND) 
This is basically the same as reading from /dev/urandom on supported
systems, only it has a limit of 256 bytes per call, and does not require
an open file descriptor (so it can be used in chroots, when resource
limits are in place, or are otherwise exhausted).

It's functionally equivalent to the comparable function getentropy(),
but has been around for longer. It's actually used to implement
getentropy in FreeBSD's libc. Discussions about adding getrandom or
getentropy to NetBSD are still ongoing.

It's present in all supported versions of FreeBSD and NetBSD.
It's not present in DragonFly or OpenBSD.

Documentation: https://netbsd.gw.com/cgi-bin/man-cgi?sysctl+7

Comparable code in OpenSSL:
ddec332f32/crypto/rand/rand_unix.c (L208)
