Mounting a temp dir into the singularity container

[nmerket]

Fixes NREL/OpenStudio-HPXML#1070

Pull Request Description

The simulation is trying to write files to /tmp inside the container. Here we're mounting a temporary directory from /tmp/scratch into it instead so there's enough room. See NREL/OpenStudio-HPXML#1071 (comment)

This one is probably outside my wheelhouse. I probably wouldn't be a very effective reviewer for this PR.

@nmerket I got my simulation working on HPC using the eagle_tmp_dir branch! Happy to share any of those files if you'd like

@mnblonsky Nice! Thanks for confirming it works. We will get this merged and in the main branch.
