remove arc4random (rc4 based)
OpenBSD arc4random is using chacha20 cipher algorithm for
a long time. This copy is still based on deprecated rc4
cipher algorithm. We could either update the arc4random.c
or drop it. Drop it. Users should better use libbsd when
using arc4random interface. Musl/glibc does not have arc4random
either.
