make-secnet-sites: New -P <prefix> option

make-secnet-sites generates a config file which defines the keys
"vpn-data", "vpn", and "all-sites".

To make it possible to usefully include the output of more than one
different piece of output from make-secnet-sites, support the option
-P <prefix>, which generates a config file which defines
"<prefix>vpn-data", "<prefix>vpn", and "<prefix>all-sites".
