Correct note about DNS randomization in openvpn.8

Commit 4880739c17b502d00a removed DNS randomization, and the dual-stack
patches for 2.4 completely changed the getaddrinfo() result handling again,
but neither fact ever made it into the man page.

+OpenVPN will try them in the order that the system getaddrinfo()
