Add test to verify that SPDX generation handles download_location
failures gracefully and doesn't crash if fetch_data_to_uri() behavior
changes.

Test verifies:
1. SPDX file generation succeeds for recipes with tarball sources
2. External references are properly structured when generated
3. ExternalRef.locator is a list of strings (SPDX 3.0 spec requirement)
4. Defensive try/except and isinstance() checks prevent crashes

The test uses m4 recipe which has tarball sources, allowing verification
of the download location handling without requiring complex setup.

Test can be run with:
  oe-selftest -r spdx.SPDX30Check.test_download_location_defensive_handling
