Double port: scapy

It looks like scapy is already a (semi-incomplete) unified Portfile, while py26-scapy is not.

Feel free to look at the differences between the two, and update scapy as needed (remember to wrap things in if(subport != name) so the virtual package scapy is just a stub while pyXX-scapy install things.

Once ready to check in those changes, delete py26-scapy as well (otherwise we'll have duplicate package for py26-scapy) :-)
