[wrynose][PATCH 2/4] spdx30: Make source download enrichment part of the task signature

[Stefano Tondo <stondo@gmail.com>]

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

bitbake does not track module functions whose names start with an
underscore when it computes task signatures. _enrich_source_package()
and _generate_git_purl() were therefore not part of the do_create_spdx
signature, and neither was SPDX_GIT_PURL_MAPPINGS, which
_generate_git_purl() reads. Changing the mappings or this code did not
rerun do_create_spdx, and the previous SPDX was restored from sstate.

Rename both functions so that bitbake tracks them. This changes the
do_create_spdx signature of every recipe once.
