trafgen: fix -t 0 option to use sendto

Currently, using -t 0 option calls shaper_set_delay with 0 sec and 0 ns,
which results in sh->type to be SHAPER_NONE. This in turn causes trafgen
to use TX_RING.

Expected behavior, from "man trafgen":

    If this option is given, then instead of packet(7)'s TX_RING
    interface, trafgen will use sendto(2) I/O for network packets, even
    if the argument is 0.

This patch forces sh->type to be set to SHAPER_DELAY even if
the delay is 0. shaper_delay already handles the case where
sh->type is SHAPER_DELAY and the delay is 0.

Fixes #208
