crypto/rand, internal/syscall/unix: add support for getentropy syscall on darwin The getentropy syscall is available on macOS since version 10.12, which is the minimum required version since Go 1.15.

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.

os/user: use libc (not cgo) on macOS With net converted to libc, os/user is the last remaining cgo code in the standard libary on macOS. Convert it to libc too. Now only plugin remains as a cgo-using package on macOS.
