parallels: set cpu mode when applying xml configuration

Otherwise exporting existing domain config and defining a new one like this:
virsh -c parallels:///system dumpxml instance01 > my.xml
virsh -c parallels:///system define my.xml
leads to an error because PCS default x64 mode turns to x32.
Thus, we need to set correct cpuMode in prlsdkDoApplyConfig() explicitly.
