[LL] Support SKIP_WHEN_OUT_OF_CONTENT_ROOT in multi-module out-of-content-root tests containing library modules

- If we don't override `createModules`, library module creation will
  fail with an exception before `SKIP_WHEN_OUT_OF_CONTENT_ROOT` is ever
  checked.
- I don't think it makes sense to add library compilation support to
  out-of-content-root tests, since out-of-content-root files should not
  be able to depend on any library.
