Subject: [PATCH] Don't look into source package provides in depsolving

Fixes regressions from commit 75ec16e660e784d7897b37cac1a2b9b135825f25:
the newly added provides of to-be-built packages were being used for
dependency resolution, such as spec satifying its own buildrequires,
and matched against conflicts in installed packages.

Source packages cannot obsolete anything or provide capabilities or files
to transactions, don't add them to rpmal at all. Explicitly skip checks
against source provides, similarly to what we already did with obsoletes.

Fixes: #1189
