Fix for VirtualSystemManagementService/13_refconfig_additional_devs.py

The cimtest case was failing because libvirt-cim improperly processed graphics devices present in the ReferenceClass parameter in DefineSystem. Rather than overrdiing them, it was appending them. With this patch, the test case now passes and the debug log shows the following correct messages.

Virt_VirtualSystemManagementService.c(1184): graphics = vnc
Virt_VirtualSystemManagementService.c(1326): Overriding device vnc from refconf
