Fix NSE trace printing of IPv6 addresses. The code was using a plain

sockaddr instead of sockaddr_storage so it got only a fraction of the
address and the inet_ntop function would look outside of the structure
into adjacent memory. A scan of localhost would look like this:

NSE: TCP ::a00:0:600:0:1234 > ::a00:4d2:0:0:25 | CONNECT

Here, for example, that 4d2 is the port number 1234 from the other
structure. Now it prints correctly:

NSE: TCP ::1:1234 > ::1:25 | CONNECT
