Add module list commands to arkouda cray-cs and cray-xc jobs
[reviewed by @ronawho]

In debugging issues with the arkouda jobs as a result of our Python 3 changes,
I found myself wanting to know more about the environment in which these jobs
were run. This change adds two module list commands to the jobs - one prior
to any modifications and one just after we expect the module list to be stable.
