vuln2json.pl: adapted to the schema more

- Provide a bogus (curl) Id and make the CVE an alias
- Add a (made up) time to the published string to make it correct syntax
- Provide URL and CWE in a "database_specific" object
- Rename 'last' to 'last_affected' within the affected ranges

Ref: #240
Closes #241
