test: gstreamer: Simplify single stream test

Browse source 
The single stream test for the GStreamer component has a simple pipeline
construction using only a fakesink.

The implementation currently supports connecting to a more complex
stream construction defined by the streamDescription, but this is over
engineered for the simple need to start a stream to capture and discard
the frames.

Convert the use of gst_parse_bin_from_description_full() which uses only
a single element 'fakesink' to construct the fakesink directly and link
it to the libcamerasrc.
