        src/lib/libc/gen: arc4random.c
        src/lib/libc/include: arc4random.h

Log Message:
arc4random(3): Switch to use thr_once (libc pthread_once symbol).

This way, we reduce the problem of arc4random initialization
fork-safety to the problem of pthread_once fork-safety -- and
anything else to do with one-time lazy initialization.

PR lib/59124: arc4random(3): first call in process races with
concurrent fork
