Notably, DisclosureDate is required for other module parsers, so let's
not ignore those, even if you have to guess at the disclosure or call
the module's publish date the disclosure date.

Add compatibility args to setuid_nmap command
Nmap before 4.75 would not run a script without a port scan being
performed. Example: 4.53 installed on Metasploitable would not work.
Added "-p80 localhost" to the command to ensure it works with these
older versions.
