libxl: support VIR_MIGRATE_PERSIST_DEST migration flag
    
    By default, virt-manager (and likely other libvirt-based apps) sets
    the VIR_MIGRATE_PERSIST_DEST flag when invoking the migrate API, which
    fails in a Xen setup since the libxl driver does not support the flag.
    
    Persisting a domain is a trivial task in the grand scheme of migration,
    so be nice to libvirt apps and add support for VIR_MIGRATE_PERSIST_DEST
    in the libxl driver.
