Bump Package Config XML file versions for Snort to 2.5.5 and fix one bug

Change Log
===================================================================

Update Snort package version in the pkg_config.8.xml and pkg_config.8.xml.amd64  master package configuration files to version 2.5.5.  Forgot to do this with the last push of new Snort package.

Fix longstanding bug in the enable/disable SID code that allows users to override default rules states by SID.  The code was not actually changing the marked SIDs because an improperly constructed array was causing a match attempt to fail.  This bug was reported again on the forums today, so I investigated.  I was previously not aware it was not working properly.  This has been broken since probably at least package version 2.5.3.
