Path error in MPI benchmark

[domcharrier]

System information

• Ubuntu 18.04 LTS
• MI50
• EPYC 7742

Describe the bug

Running the OpenMPI benchmarks result in a crash due to command
mkdir -p /RET_MPI/omb.

A folder RET_MPI exists in the RET root directory. I suspect
the above path should point to this directory.

To Reproduce:

# cd <RET-root>
sudo ./ret install rocm
sudo ./ret install mpi

Expected behavior

Benchmarks complete without errors.
