[submit_mdt_analyses_lintf2_ether.py]: Use Absolute Path to Slurm Script

So far, the Python submit script did not submit the Slurm job script
from the same directory as the Python submit script but from the
`${PATH}` variable.

Now, absolute paths are used to submit the Slurm job scripts that lie
within the same directory as the Python submit script.
