conntrack: add display support for sctp

Currently, only the netlink datapath supports SCTP connection tracking,
but at least this removes the warning message that will pop up when
running something like:

   ovs-appctl dpctl/dump-conntrack

This doesn't impact any conntrack functionality, just the display.
