vulndb/internal/audit: filter out vulns for modules with "" version

When a module version is unknown (""), the current implementation assumes
that any vulnerability version range applies to it. This can lead to
false alarms, the most prominent example being when audit is run on a
top-level module (which will have "" version) that has known
vulnerabilities. This CL makes sure no vulnerabilities apply for a
module with an unavailable version.

Fixes golang/go#48079

PkgGoDev

This subrepository holds experimental and deprecated (in the old directory) packages.

The idea for this subrepository originated as the pkg/exp directory of the main repository, but its presence there made it unavailable to users of the binary downloads of the Go installation. The subrepository has therefore been created to make it possible to go get these packages.

Warning: Packages here are experimental and unreliable. Some may one day be promoted to the main repository or other subrepository, or they may be modified arbitrarily or even disappear altogether.

In short, code in this subrepository is not subject to the Go 1 compatibility promise. (No subrepo is, but the promise is even more likely to be violated by go.exp than the others.)

Caveat emptor.
