MINOR: stream: report the current filter in "show sess all" when known

Filters can block the stream on pre/post analysis for any reason and it can
be useful to report it in "show sess all". So now, a "current_filter" extra
line is reported for each channel if a filter is blocking the analysis. Note
that this does not catch the TCP/HTTP payload analysis because all
registered filters are always evaluated when more data are received.
