topology: Fix missing stream name of widgets in text conf file

Browse source 
User can define the stream name of an input/output widget in the text conf
file, by setting "stream_name" of a SectionWidget.

Topology C API and kernel already have support for configuring a widget's
stream name. This patch just adds the missing part of the text conf file.
