Title: Cleanup lingering pipes from previous runs.

While not technically harmful (Riak and to_erl do just fine), the extra files in PIPE_DIR confuse the Ruby client tests, which expect only one set of FIFOs to be present. Since we start the nodes from a clean state, but PIPE_DIR lives outside the node roots, it seems reasonable to clean them up before starting a test, at least until the Ruby client can identify and ignore stale FIFOs.
