datapath: Hardcode vport multicast group ID on older kernels.
Older kernels do not advertise the multicast groups of families
when requested by userspace. As a workaround, this patch hardcodes
the multicast group ID of the ovs_vport family on these kernels.
Userspace will be able to fall back to this hardcoded value if the
standard mechanism is unavailable.
