Previously, Syft would attempt to dereference pom variables, but if it
detected a cycle or failed to get back to a non-variable value, it would
return the last variable. Instead, return an empty string. Otherwise,
certain jars will have versions like "${project.version}" in the SBOM,
which is not helpful.

This is a follow up to #2783 and improves the behavior around #2776.
