[PATCH 3/3] oeqa/selftest: Add tests for source download enrichment

[Stefano Tondo <stondo@gmail.com>]

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

test_gitsm_source_version builds git-submodule-test, which uses gitsm,
and checks that its source download carries the SRCREV as version.

test_git_purl_mappings_rerun_create_spdx builds fastfloat twice, first
with the default mapping and then with github.com mapped to another
PURL type, and checks that the second SPDX carries the new PURL. Before
the enrichment became part of the task signature, the second build
restored the first SPDX from sstate.
