[RFC PATCH 1/4] KVM: selftests: Guard struct kvm_vcpu_events with __KVM_HAVE_VCPU_EVENTS

[Thomas Huth]

The struct kvm_vcpu_events code is only available on certain architectures
(arm, arm64 and x86). To be able to compile kvm_util.c also for other
architectures, we've got to fence the code with __KVM_HAVE_VCPU_EVENTS.
