lib.sh: Use host-passthrough when spawning VMs
virsh defaults to using "host-model" instead of "host-passthrough",
which not only might lead to a small performance hit on x86, it is
also causing compatibility issues with libvirt 3.x.
Address this by explicitly requesting "host-passthrough" as the
CPU model for virt-install.
