etnaviv: add set_stream_output_targets(..) stub

When running gles3 deqp's with ETNA_MESA_DEBUG=deqp we fake streamout support.
CSO thinks that streamout is supported and calls ctx->pipe->set_stream_output_targets(..)
in cso_destroy_context(..) which results in a null-pointer access.

Add a stub to make development easier.
