Set the number of launcher cores per locale for Cray CS perf testing

[reviewed by @gbtitus]

Some nodes in the partition have hyperthreading disabled, which changes
the automatic core counting with do with sinfo. Hard code to 72 to
avoid that. For configs that use slurm-srun (ofi) this was causing us to
only request access to half the cores, which limited performance.
