RHEL >= 9.0 on x86_64 requires the processor to support the "x86-64-v2" microarchitecture level, which the default QEMU VCPU model does not satisfy. Activate host-passthrough for such guest OSes.
(Libosinfo does not track processor support, so in the future we may have to extend the expression added in this patch to other distros.)
