Update CSTP for IPv6 DNS servers

When the Cisco side is configured with IPv4 and IPv6 DNS resolver IPs,
it will send option X-CSTP-DNS-IP6
This patch captures the IPv6 addresses provided, and puts them in
INTERNAL_IP6_DNS variable for vpnc-scripts (which is already handled
there)

[dwmw2: Put them in $INTERNAL_IP4_DNS instead. They shouldn't be split.]
