include: update virtio UAPI headers

Commit a08bb43a0c37 ("kvmtool: Copy Linux' up-to-date virtio headers")
copied the kernel's virtio UAPI headers into the kvmtool tree, because
at the time some distros didn't include (all of) them in their kernel
headers package.
Let's update those copies, so that we can use newer features, if needed.

This syncs in the already existing copies of the headers from Linux
v5.18.0.
