test: gstreamer: Remove videoconvert element from pipeline

The GStreamer single stream test uses the following pipeline:

	libcamerasrc ! videoconvert ! fakesink

The videoconvert element isn't useful as the data is thrown away by the
fakesink anyway. We can shorten the pipeline to

	libcamerasrc ! fakesink

to save CPU time and to avoid depending on the gstreamer1.0-plugins-base
package to run the unit tests.

The test could be further simplified by replacing
gst_parse_bin_from_description_full() with gst_element_factory_make(),
now that we only add one element to the bin. The extra cost incurred by
the bin only impacts initialization time, and using a bin will make it
easier to add other elements in the future if needed. Keep the bin, and
only drop the videoconvert element.
