MINOR: rules: record the last http/tcp rule that gave a final verdict

When a tcp-{request,response} content or http-request/http-response
rule delivers a final verdict (deny, accept, redirect etc), the last
evaluated one will now be recorded in the stream. The purpose is to
permit to log the last one that performed a final action. For now
the log is not produced.
