gstreamer-base/basesink: Provide default implementation for render

Browse source 
We need some classes derived from `BaseSink` to not enforce render being
implemented.

An example of this is AudioSink which only requires the user to
implement `write` but not `render`, so the default implementation
of render needs to be called.
