scripts/update-linux-headers.sh: pull virtio hdrs
It doesn't make sense to copy values manually: the only issue with getting headers from linux seems to be dealing with linux/types, we can easily fix that automatically while importing. Signed-off-by: Michael S. Tsirkin <mst@redhat.com> Reviewed-by: Thomas Huth <thuth@linux.vnet.ibm.com>
