tests/run-tests.py: Add list of passed/skipped tests to _result.json.

The output `_result.json` file generated by `run-tests.py` currently
contains a list of failed tests.  This commit adds to the output a list of
passed and skipped tests, and so now provides full information about which
tests were run and what their results were.
