Wrap rand.Reader in a bufio.Reader.
rand.Read() results in a syscall to the host on every call instead we can wrap it with a bufio.Reader to buffer and reduce number of syscalls. This is especially important for TCP where every newly created endpoint reads random data to initialize the timestamp offsets for the endpoint. Updates #231 PiperOrigin-RevId: 301501607
