LU-676 tests: machinefile option for mpirun via a variable

Not all MPI implementations pass the host file to mpirun via the same
option. Common options are -machinefile and -hostfile.

This problem can be resolved by using a variable MACHINEFILE_OPTION
instead. A default value is assigned if the variable not defined.
