Disable zoltan testing

There is very little zoltan functionality used by seacas.
Disable the zoltan testing and test setup for seacas builds
to reduce significantly the amount of work done for a seacas
build. May reverse this in the future and it is good to test zoltan
periodically, but the zoltan developers and Trilinos builds do the
testing, so hopefully that will catch issues.
