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

To pick the changes in:

  f7ab71f ("KVM: s390: Add explicit padding to struct kvm_s390_keyop")
  0ee4ddc ("KVM: s390: Storage key manipulation IOCTL")
  fa9893f ("KVM: Introduce KVM_EXIT_SNP_REQ_CERTS for SNP certificate-fetching")
  f174a9f ("KVM: arm64: Add exit to userspace on {LD,ST}64B* outside of memslots")

That just rebuilds perf, as these patches add just one new KVM ioctl,
but for S390, that is not being considered by tools/perf/trace/beauty/kvm_ioctl.sh
so far.

This addresses this perf build warning:

  Warning: Kernel ABI header differences:
    diff -u tools/include/uapi/linux/kvm.h include/uapi/linux/kvm.h

Please see tools/include/uapi/README for further details.
