tests: Avoid use of virQEMUDriverCreateXMLConf(NULL)

Browse Source 
We use the function to create a virDomainXMLOption object that is
required for some functions. However, we don't pass the driver
pointer to the object anywhere - rather than pass NULL. This
causes trouble later when parsing a domain XML and calling post
parse callbacks:

  Program received signal SIGSEGV, Segmentation fault.
