[Libguestfs] [PATCH v2v] -o libvirt: Use cpu='host-model' for gcaps_default_cpu = false

For RHEL >= 9 / x86-64 guests we cannot use the default qemu CPU (eg. "qemu64"), and so we have a mechanism for conversion to indicate to the output modes that a more capable CPU is required. We previously picked cpu='host-passthrough' (ie. the equivalent of qemu's -cpu host). However this is not live migratable. cpu='host-model' is a better choice as it is more likely to be migratable.
