MINOR: stream: Remove tests on the option 'http-use-htx' in stream_new()

All streams created for an HTTP proxy must now use the HTX internal
resprentation. So, it is no more necessary to test the flag PR_O2_USE_HTX. It
means a stream is an HTX stream if the frontend is an HTTP proxy or if the
frontend multiplexer, if any, set the flag MX_FL_HTX.
