[PATCH] qemuxmlconftest: Add test cases for broken and missing XML files

Add test cases for few edge cases which excercise the XML reporting from libxml2 in anticipation of upcoming changes of behaviour. 'virschematest' must skip parsing of the broken file altogether so this patch adds infrastructure to allow that.
