vuln2json.pl: adapted to the schema more

[bagder]

• 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

Reported-by: Oliver Chang

Ref: #240

Example

The first JSON object now looks like this:
