Subject: tools headers uapi: Update tools's copies of kvm headers

To get the changes in:

	a449938297e5 ("KVM: s390: Add huge page enablement control")
	8fcc4b5923af ("kvm: nVMX: Introduce KVM_CAP_NESTED_STATE")
	be26b3a73413 ("arm64: KVM: export the capability to set guest SError syndrome")
	b7b27facc7b5 ("arm/arm64: KVM: Add KVM_GET/SET_VCPU_EVENTS")
	b0960b9569db ("KVM: arm: Add 32bit get/set events support")
	a3da7b4a3be5 ("KVM: s390: add etoken support for guests")

This makes 'perf trace' automagically get aware of these new ioctls:

  $ cp include/uapi/linux/kvm.h tools/include/uapi/linux/kvm.h
  $ tools/perf/trace/beauty/kvm_ioctl.sh  > /tmp/after
  $ diff -u /tmp/before /tmp/after

And cures the following warning during perf's build:

	diff -u tools/include/uapi/linux/kvm.h include/uapi/linux/kvm.h
