ipdemux: Better initial so_port distribution for non-power-of-2 ncpus

The measured effect of this change on 2-ways E5-2600v2 with Intel 82599
(10Gbe) using tools/kq_connect_client -u, i.e. UDP socket/connect/send/
close before initiating a TCP connection:
- Connect rate increases by ~15Kconns/s; we are now doing 315Kconns/s.
- This also improves tools/kq_connect_client w/o -u a little bit.
