vhost: fix C++ include

The virtio kernel header includes are already noted as being
incompatible with C++. We can ensure that the header is safe for
inclusion in C++ code by not including those headers during C++ builds.
While not ideal, this does ensure that all DPDK headers can be included
in C++ code without errors.
