tools headers: Sync copy of kvm UAPI headers
In 801e459a6f ("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
--- /tmp/kvm_ioctl_array.c 2018-03-05 11:55:38.409145056 -0300
+++ /tmp/build/perf/trace/beauty/generated/ioctl/kvm_ioctl_array.c 2018-03-05 11:56:17.456153501 -0300

[0x04] = "GET_VCPU_MMAP_SIZE",
[0x05] = "GET_SUPPORTED_CPUID",
[0x09] = "GET_EMULATED_CPUID",
+ [0x0a] = "GET_MSR_FEATURE_INDEX_LIST",
[0x40] = "SET_MEMORY_REGION",
[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:

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'
