LU-13283 tests: add racer to nonmpi load

Patch adds the ability to run racer as one of
nonmpi loads. All racer parameters can be set over
RACERP:
Example:
  RACERP="MDSCOUNT=3 DURATION=600 RACER_ENABLE_STRIPED_DIRS=false"
etc.

ha_start_mpi_loads() is improved to not create
machinefiles if no mpi load set.
