[Piglit] [PATCH] CL: don't reporting failed cases as PASS

If in multiple subtests, first failed, last passed, then subtests
was looked as "passed". Because "interpretResult" function overwrote
previous results. See framework/exectest.py, interpretResult():

	     if piglit.startswith('subtest'):
		 if not 'subtest' in results:
		     results['subtest'] = {}
HERE->           results['subtest'].update(eval(piglit[7:]))

For instance, if test result was
 ["subtest {'clz char1' : 'fail'}", "subset {'clz char1' : 'pass'}"]
then results['subtest'] would be 'pass'.

"doRun" function also overwrote old results. See framework/core.py,

         if 'subtest' in result and len(result['subtest'].keys()) > 1:
             for test in result['subtest'].keys():
HERE->           result['result'] = result['subtest'][test]

Thus if some subtests failed, but others passed, then final result might
be "PASS".

This patch fixes the bug.
