spack audit: allow skipping version checks from package.py (#28372)

A few packages have version directives evaluated
within if statements, conditional on the value of
`platform.platform()`.

Sometimes there are no cases for e.g. platform=darwin and that
causes a lot of spurious failures with version existence
audits.

This PR allows expressing conditions to skip version
existence checks in audits and avoid these spurious reports.
