Test compare_configs.py

TODO(epoger): Create a command to update the expected results (in
self._output_dir_expected) when appropriate.  For now, you should:
1. examine the results in self._output_dir_actual and make sure they are ok
2. rm -rf self._output_dir_expected
3. mv self._output_dir_actual self._output_dir_expected
Although, if you're using an SVN checkout, this will blow away .svn directories
within self._output_dir_expected, which wouldn't be good...
