qemu: Always send persistent XML during migration

Browse Source 
When persistent migration of a transient domain is requested but no
custom XML is passed to the migration API we would just let the
destination daemon make a persistent definition from the live definition
itself. This is not a problem now, but once the destination daemon
starts replacing the original CPU definition with the one from migration
cookie before starting a domain, it would need to add more ugly hacks to
reverse the operation. Let's just always send the persistent definition
in the cookie to make things a bit cleaner.
