support/scripts/pkg-stats: ignore packages with no valid infra and no version for...

Virtual packages (with in pkg-stats speak have "no valid
infrastructure") and packages that have no version specified cannot be
used for CVE checking. They trigger a bunch of warnings from the CVE
checking code, as it cannot parse their version: they don't have any
version. So instead, we simply skip those packages.

A follow-up commit will improve the reporting to be able to
distinguish those packages from packages that have seen their CVEs
checked and don't have any reported.
