Make sure to create a default emulator device for XenFV domains

This adds the emulator device in once we go to create the actual domain
object (and thus determine if the type necessitates an <emulator>.

This should fix definesystem on XenFV, although some other things
surrounding the NetRASD stuff in progress now may prevent regular testing
of it.
