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.

kvmtool: Copy Linux' up-to-date virtio headers

Some distributions with an older uapi header copy do not have all the
definitions that we need (Ubuntu 12.04 comes to mind).
So copy the latest versions from the Linux tree to override the system
header versions.
Also include virtio_mmio.h, which is technically not an uapi header,
but is used in such a way. QEMU has actually a copy of these
definitions in its own header file, so our approach should even be
better.
Those files are from a Linux v4.1-rc6 source tree, but the virtio-1.0
updates have been left out. kvmtool implements only the older version
of virtio.
