Fix: Delete stream on write error in consumer

Whenever a write() error occured, both on network or local trace file,
the consumer thread just died considering the error a fatal one.

This commit fixes that by simply deleting the stream, removing it from
the poll set of the thread and freeing it.

Furthermore, on a write() error, a SIGPIPE is usually raised if the FD
is invalid. The consumer is catching this signal but was initiating a
should exit action thus ultimately cleaning all threads. We now still
catch SIGPIPE but don't set the should quit flag so normal cleanup can
be done by the threads.
