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

To pick the changes in:

  6d8491910fcd3324 ("KVM: x86: Introduce KVM_CAP_DISABLE_QUIRKS2")
  ef11c9463ae00630 ("KVM: s390: Add vm IOCTL for key checked guest absolute memory access")
  e9e9feebcbc14b17 ("KVM: s390: Add optional storage key checking to MEMOP IOCTL")

That just rebuilds perf, as these patches don't add any new KVM ioctl to
be harvested for the the 'perf trace' ioctl syscall argument
beautifiers.

This is also by now used by tools/testing/selftests/kvm/, a simple test
build succeeded.

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'
