Rollup merge of #66092 - niacat:master, r=nagisa
Use KERN_ARND syscall for random numbers on NetBSD, same as FreeBSD. This system call is present on all supported NetBSD versions and provides an endless stream of non-blocking random data from the kernel's ChaCha20-based CSPRNG. It doesn't require a file like `/dev/urandom` to be opened. The system call is documented here (under kern.arandom): https://netbsd.gw.com/cgi-bin/man-cgi?sysctl+7+NetBSD-7.0 And defined here: https://nxr.netbsd.org/xref/src/sys/sys/sysctl.h#273 The semantics are the same as FreeBSD so reading 256 bytes per call is fine. Similar change for getrandom crate: rust-random/getrandom#115
