nfs: add server port to rpc_pipe info file

On the server side, when sending krb5 callbacks to the client, gssd needs to know the callback port.

Together with an nfs-utils patch, this also allows us to support krb5 mounts of servers using non-standard ports; currently if you specify an alternate server port on the commandline the mount fails.

I don't know whether appending an extra "port:" line here is the right approach, though. Comments?
