[OE-core][PATCH v11 4/4] oeqa/selftest: Add tests for source download enrichment

[stondo@gmail.com]

From: Stefano Tondo <stefano.tondo.ext@siemens.com>

Add two new SPDX 3.0 selftest cases:

test_download_location_defensive_handling:
  Verifies SPDX generation succeeds for recipes with tarball sources
  and that external references are properly structured (ExternalRef
  locator is a list of strings per SPDX 3.0 spec).

test_version_extraction_patterns:
  Verifies that version extraction works correctly and all source
  packages have proper version strings containing digits.

These tests validate the source download enrichment added in the
previous commit.
