Fix Cardano CLI tests on MacOS:

    * Introduce DATE and SED environment variables to switch betweed date
      and gdate; and sed and gsed for MacOS/Linux compatibility.
    * Use xargs to strip whitespace from either side of the line count so
      that line count comparisions work on MacOS
    * Use bash instead of sh to avoid shell lint error on used of type
      shell command
