NMI bulid glue - don't run ctest in the batlab's tasks for creating tarballs,
because when you do and tests fail, you don't get any tarballs out of the batlab!
this patch makes running ctest in the batlab a separate task.
this reverses #3230, as well as the original decision to run make test
as part of the create_unstripped_tar task.
