tools/virtio: update internal copies of headers

The virtio headers have changed recently:

 5b1bf7cb673 virtio_ring: let virtqueue_{kick()/notify()} return a bool
 46f9c2b925a virtio_ring: change host notification API

Update the internal copies to fix the build of virtio_test:

  cc -g -O2 -Wall -I. -I ../../usr/include/ -Wno-pointer-sign
    -fno-strict-overflow -fno-strict-aliasing -fno-common -MMD -U_FORTIFY_SOURCE
    -c -o virtio_test.o virtio_test.c
