With the SCTP checksum offload support added to virtio, it is
now possible to get into a situation where SCTP not present
in the kernel, but the feature is negotiated. Handle this just
like we do IPv6 and other modular offloads.
Move the sctp offload out of the sctp module and into the base
kernel.
