This patch includes multiple fixes for the `dev/test-dependencies.sh` script (which was introduced in #10461):

- Use `build/mvn --force` instead of `mvn` in one additional place.
- Explicitly set a zero exit code on success.
- Set `LC_ALL=C` to make `sort` results agree across machines (see https://stackoverflow.com/questions/28881/).
- Set `should_run_build_tests=True` for `build` module (this somehow got lost).
