etnaviv: Add util_blitter_save_so_targets(..) call

We do not support stream outputs yet so be better at faking it.
Fixes the following assertion when running deqp-gles3:
 u_blitter.c:635: blitter_check_saved_vertex_states: Assertion `!ctx->has_stream_out || ctx->base.saved_num_so_targets != ~0u' failed
