Bug fix for /proc/net/if_conntrack and /proc/net/nf_conntrack files

The optional security info was errorneously parsed as a "long" when
it's really a string of characters.  The ProcNetNFCONNTRACK and
ProcNetIPCONNTRACK both needed the fix.

Also, the JSON/CSV files for both files were updates and the
recreators needed a minor tweak as well.
