Ensure that the output path used by perf_tests_test matches the path used by perf_tests if the FLUTTER_TEST_OUTPUTS_DIR variable is set (#153888)

Browse Source 
A recent change to the flutter_drone recipe is setting FLUTTER_TEST_OUTPUTS_DIR in the environment (see https://flutter.googlesource.com/recipes/+/b111cd3ef2297e66905cc48c2cfedce0cf1ba46f)

If FLUTTER_TEST_OUTPUTS_DIR is set, then perf_tests will use an output path based on that variable.  perf_tests_test needs to use the same logic when looking for the expected output file.
