closedlibhtp: don't put stream in error state on compression issues

Description
If we have a response body that takes too long to unpack we may have someone trying to trick us, but it could also be a bit random due to system load (as we experience in QA currently). We shouldn't put the entire stream in an error state, but instead skip the rest of the body in the offending tx. Perhaps it would make sense to count the number of txs in a stream that trigger this and have some threshold for putting the stream in an error state to reduce the effect of truly malicious streams.

Related question, should we use getrusage(RUSAGE_THREAD
rather than gettimeofday
? (does it make more sense ?)
