Now replace "KVM features" with "CPU fatures", because all CPU features
are KVM features, as all of them depend on KVM code enabling them on
GET_SUPPORTED_CPUID.
Thus, the global flag to only enable explicitly request KVM features on
CPUs is "-cpu custom", which doesn't enable any CPU feature at all.
