security/openvpn override for dfports

Quote from openvpn.sf.net:
"OpenVPN is an easy-to-use, robust, and highly configurable VPN (Virtual 
Private Network) daemon which can be used to securely link two or more 
private networks using an encrypted tunnel over the internet"
End of qoute...

It does not compile on dfly, because it can not find TUNSLMODE and 
TUNSIFHEAD. This patch adds files/patch-aa to openvpn port structure in 
order to make it compile properly.
