bug#47188: "guix lint -c cve" does not account for language prefixes (rust-, python-, go-, ..)

Hi,

Yes, that’s an issue.  We can address these by adding a ‘cpe-name’
property (info "(guix) Invoking guix lint"), but that’s going to be
tedious.  We can at least add it to high-profile packages for now.

Tooling that suggests or deduces the CPE name would help a lot:
