veth: add kernel header linux/veth.h for VETH defines

Similar to what's done with <linux/if_link.h>, make sure used defines actually exist. Otherwise building on even slightly older kernels fails. Taken from upstream kernel commit 1860e379875dfe7271c649058aeddffe5afd9d0d (tag: v3.15), file 'include/uapi/linux/veth.h'.
