Fix singularity image

[NucciTheBoss]

Purpose

Pull request fixes tzdata data-entry issue brought up in issue #4365.

Changelog

1. Set timezone to Etc/UTC to make tzdata data-entry prompt go away.
2. Updated base image to nvidia/cuda:10.1-cudnn7-devel-ubuntu18.04. g++ was too old to compile numpy in the old base image.
3. Removed make in apt-get install -y --no-install-recommends. make is provided by the build-essential package.
4. Added missing dependencies to apt-get install -y --no-install-recommends. Needed gfortran, liblapack-dev, libopenblas-dev, and libhdf5-dev.
5. Added some code styling to build recipe.

Testing

Had some of the consultants I work with run tests on our cluster. Did not encounter any runtime errors.

What's next

Updating Dockerfile and singularity recipe to newer version of pytorch_geometric.

LGTM. We could upgrade to a reasonable PyTorch version in a later PR.

[NucciTheBoss]

Added explanation comment for setting timezone to recipe. Should be good to go.
