For cpu-only builds, laghos experiment.py sets n_ranks equal to n_nodes instead of n_nodes * sys_cores_per_node

Steps to reproduce the behavior:

Run bin/benchpark experiment init --dest=laghos laghos +strong ~single_node caliper=mpi
Open laghos/ramble.yaml
Check the value of n_ranks variable

Expected behavior
n_ranks should be equal to n_nodes * sys_cores_per_node

Supercomputer (please complete the following information):

system: Dane
system parameters: llnl-cluster cluster=dane
experiment: laghos
experiment parameters: laghos +strong ~single_node caliper=mpi
