cuda-9.0: Rebuild to update cudnn from 7.0 to 7.3.1

Binary (wheel) download of tensorflow seems to require cuda-9.0 and
cudnn>=7.2.1.

Error with newer cuda:

    ImportError: libcublas.so.9.0: cannot open shared object file: No such
    file or directory

Error with older cudnn:

    Loaded runtime CuDNN library: 7.0.5 but source was compiled with:
    7.2.1.  CuDNN library major and minor version needs to match or have
    higher minor version in case of CuDNN 7.0 or later version. If using
    a binary install, upgrade your CuDNN library.  If building from
    sources, make sure the library loaded at runtime is compatible with
    the version specified during compile configuration.

We can only select from versions offered by nvidia. cudNN 7.2.* os not
available there. SO use latest for cuda 9.0 which is 7.3.1.20 currently.
