virt: detect KubeVirt instance

Kubevirt is currently technically based on KVM (but not xen yet[1]).
The systemd-detect-virt command, used to differentiate the current
virtualization environment, works fine on x86 relying on CPUID, while
fails to get the correct value (none instead of kvm) on aarch64.

Let's fix this by adding a new 'vendor[KubeVirt] = kvm' classification
considering the sys_vendor is always KubeVirt.
