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

To pick the changes in:

  15fb7de1 ("KVM: SVM: Add KVM_SEV_RECEIVE_UPDATE_DATA command")
  3bf72569 ("KVM: arm64: Add support for the KVM PTP service")
  4cfdd47d ("KVM: SVM: Add KVM_SEV SEND_START command")
  54526d1f ("KVM: x86: Support KVM VMs sharing SEV context")
  5569e2e7 ("KVM: SVM: Add support for KVM_SEV_SEND_CANCEL command")
  8b13c364 ("KVM: introduce KVM_CAP_SET_GUEST_DEBUG2")
  af43cbbf ("KVM: SVM: Add support for KVM_SEV_RECEIVE_START command")
  d3d1af85 ("KVM: SVM: Add KVM_SEND_UPDATE_DATA command")
  fe7e9488

 ("KVM: x86: Add capability to grant VM access to privileged SGX attribute")

That don't cause any change in tooling as it doesn't introduce any new
ioctl.

  $ grep kvm tools/perf/trace/beauty/*.sh
  tools/perf/trace/beauty/kvm_ioctl.sh:printf "static const char *kvm_ioctl_cmds[] = {\n"
  tools/perf/trace/beauty/kvm_ioctl.sh:egrep $regex ${header_dir}/kvm.h	| \
  $
  $ tools/perf/trace/beauty/kvm_ioctl.sh > before
  $ cp include/uapi/linux/kvm.h tools/include/uapi/linux/kvm.h
  $ tools/perf/trace/beauty/kvm_ioctl.sh > after
  $ diff -u before after
  $

This silences this perf build warning:

  Warning: Kernel ABI header at 'tools/include/uapi/linux/kvm.h' differs from latest version at 'include/uapi/linux/kvm.h'
  diff -u tools/include/uapi/linux/kvm.h include/uapi/linux/kvm.h
