Fix ascii writer to not discard a ".gz" file extension

Browse source 
When Bro writes a compressed log, it uses a file extension of ".gz".
However, upon log rotation the ascii writer script function
"default_rotation_postprocessor_func" was discarding the ".gz"
file extension.  Fixed so that the correct file extension is
preserved after rotation.
