[LIT] Fix failing LIT tests

Summary:
I spend some time trying to get the LIT test suite passing. Here are the changes that I needed to make on my machine.

I made the following changes for the following reasons.

1. google-test.py: The Google test format now checks for "[  PASSED  ] 1 test." to check if a test passes.
2. discovery.py: The output appears in a different order on my machine than it did in the test.
3. unittest-adaptor.py: The output appears in a different order on my machine than it did in the test.
4. The classname is now formed differently in `getJUnitXML(...)`.

I'm not sure what is causing the output order to differ in discovery.py and unittest-adaptor.py. Does anybody have any thoughts?
