run-test.sh: inherit unified stdout capture from init_env

- Source ./init_env first so global tee is activated once per session.
- Remove any per-script capture logic; rely on exported RUN_STDOUT_FILE.
- Ensure child ./run.sh inherits the environment unchanged (no semantic changes).
- Minor cleanup to avoid duplicate env setup; logging remains via functestlib.
