crypto/rand: use arc4random(3) on macOS and iOS
It's been good since Sierra: it never fails, it's faster, it's available
on iOS (see #47812), and it still handles forks and reseeding.
On a M2 with macOS 14.3.1:
│ sec/op │ sec/op vs base │
Read/32-8 413.7n ± 3% 249.7n ± 3% -39.65% (p=0.000 n=10)
Read/4K-8 7.097µ ± 6% 1.261µ ± 2% -82.24% (p=0.000 n=10)
│ B/s │ B/s vs base │
Read/32-8 73.76Mi ± 3% 122.25Mi ± 3% +65.73% (p=0.000 n=10)
Read/4K-8 550.5Mi ± 6% 3099.0Mi ± 2% +462.99% (p=0.000 n=10)
arc4random(3) would be a good replacement for getentropy(2) on FreeBSD
and NetBSD as well, but we don't get as easy access to libc there.
