Ensure singularity compatibility

Make sure that the image is also usable with singularity.

keine Ahnung wie man hier nen merge request macht, aber hier eine Variante, wie es funktioniert. damit es mit singularity klappt, muss man nur die Umgebungsvariablen setzten im Dockerfile via

ENV ROOTSYS=/opt/root
ENV PATH=$ROOTSYS/bin:$PATH
ENV LD_LIBRARY_PATH=$ROOTSYS/lib:$LD_LIBRARY_PATH   

Oh great, I'll try it.
