Subject: [PATCH] benchmark: Fix crash in net benchmarks

Net benchmarks create partial event emitters that do not have all of the
required event emitter functions. They currently mock out `on`, `once`,
and `emit` functions. This change mocks out `prependListener` as well to
avoid crashing in `_stream_readable`.
