Report correct test suite names for opt-testcases/* in outcome file
Report correct test suite names for opt-testcases/* in outcome file

In the outcome file, report each test case in the file it's in, rather than
reporting them all from ssl-opt. This is more informative and matches what
check_test_cases.py does.

This fixes a bug whereby test cases from opt-testcases/* were not detected
as having run on the CI, because analyze_outcomes.py (which uses
check_test_cases.py) expects them in the containing file whereas they were
reported in ssl-opt.
