qemuxmlactivetest: Add qemu active XML to active/inactive XML tests

Add explicit test cases for XMLs from qemuxml2argvdata which
historically had different output in qemuxml2xmltest.

qemuxmlactivetest explicitly ensures that the input XMLs are parsed in
'live' state and formatted both in inactive as well as live state,
rather than the previously present inactive->inactive,  live->live tests
only.

The XMLs picked in this case are those which had separate output files
in qemuxml2argvtest.
