qemuxml2argvtest: Parse 'arch' from XML early

If we want to provide correct (fake) caps already for the XML parser we
need to be able to parse the arch early so that we can properly
initialize the caps cache prior to calling the XML parser.

This patch adds code which parses the arch and updates the caps cache
prior to the parse step.
