    libxl: Allow network driver domains when run_hotplug_scritps is set
    
    As of commit 05bfd984dfe7014f1f5ea1133608b9bab589c120, hotplug scripts
    are not run if backend_domid != LIBXL_TOOSTACK_DOMID; so there is no reason
    to restrict this for network driver domains any more.
    
    This is a candidate for backporting to 4.3.
