tools headers uapi: Sync linux/kvm.h with the kernel sources
To get the changes from these csets:
2bc39970e932 ("x86/kvm/hyper-v: Introduce KVM_GET_SUPPORTED_HV_CPUID")
2a31b9db1535 ("kvm: introduce manual dirty log reprotect")
That results in these new KVM IOCTLs being supported in 'perf trace'
when beautifying the cmd ioctl syscall argument:
$ cp include/uapi/linux/kvm.h tools/include/uapi/linux/kvm.h
$ tools/perf/trace/beauty/kvm_ioctl.sh > after

At some point we should be able to do something:
# perf trace -e ioctl(cmd == KVM_CLEAR_DIRTY_LOG)
And have just those ioctls, optionally with callchains, etc.
