target/arm/kvm.c checked PMU availability but claimed PMU is
available even if it is not. In fact, Asahi Linux supports KVM but lacks
PMU support. Only advertise PMU availability only when it is really
available.

Fixes: dc40d45ebd8e ("target/arm/kvm: Move kvm_arm_get_host_cpu_features and unexport")
