tools headers: Sync copy of kvm UAPI headers

In 801e459a6f3a ("KVM: x86: Add a framework for supporting MSR-based features") a new ioctl was introduced, which with this sync of the kvm UAPI headers, makes 'perf trace' know about it:

  $ cd /tmp/build/perf/trace/beauty/generated/ioctl/
  $ diff -u kvm_ioctl_array.c.old kvm_ioctl_array.c

 	[0x41] = "CREATE_VCPU",
 	[0x42] = "GET_DIRTY_LOG",

So when using 'perf trace -e ioctl' that will appear along with the others, like in this excerpt of a system wide session:

14.556 ( 0.006 ms): CPU 0/KVM/16077 ioctl(fd: 19<anon_inode:kvm-vcpu:0>, cmd: KVM_RUN) = 0

This also silences the perf build header copy drift verifier:

make: Entering directory '/home/acme/git/perf/tools/perf'
BUILD: Doing 'make -j4' parallel build
Warning: Kernel ABI header at 'tools/include/uapi/linux/kvm.h' differs from latest version at 'include/uapi/linux/kvm.h'
