virt-install's --cpu host maps to libvirt's

  <cpu mode='host-model'/>

while virt-install's --cpu host-passthrough maps to libvirt's

  <cpu mode='host-passthrough'/>

These semantics are not architecture dependent and, while the choice
of name is a bit unfortunate considering that QEMU's -cpu host and
virt-install's --cpu host have different meanings, I think they're
completely unambiguous and reasonably documented, and we should not
mess with them.
