upstream OpenBSD: arc4random: replace abort() with _exit()
In the incredibly unbelievable circumstance where _rs_init() fails to
allocate pages, don't call abort() because of corefile data leakage
concerns, but simply _exit(). The reasoning is _rs_init() will only fail
if someone finds a way to apply specific pressure against this failure
point, for the purpose of leaking information into a core which they can
read. We don't need a corefile in this instance to debug that. So take
this "lever" away from whoever in the future wants to do that.
