Updated making mmap-able model part of README.md

In the making mmap-able model part of the REAMDE.md file, there is no mention of providing `convert_graphdef_memmapped_format` as the artifact name for `taskcluster.py` file. Without this argument `taskcluster.py` file tries to download the default `native_client.tar.xz` artifact and the code receives a 404 error.

The `output_graph.pb` model file generated in the above step will be loaded in memory to be dealt with when running inference.
This will result in extra loading time and memory consumption. One way to avoid this is to directly read data from the disk.
TensorFlow has tooling to achieve this: it requires building the target `//tensorflow/contrib/util:convert_graphdef_memmapped_format` (binaries are produced by our TaskCluster for some systems including Linux/amd64 and macOS/amd64), use `util/taskcluster.py` tool to download, specifying `tensorflow` as a source.

Producing a mmap-able model is as simple as:
```
$ convert_graphdef_memmapped_format --in_graph=output_graph.pb --out_graph=output_graph.pbmm
