tools headers UAPI: Sync kvm.h headers with the kernel sources

To pick the changes in:

  fb04a1eddb ("KVM: X86: Implement ring-based dirty memory tracking")

That result in these change in tooling:

Now one can use that string in filters when tracing ioctls, etc.

And silences this perf build warning:
