As a workaround for #78, a fix was submitted which removes the /tmp/NuGetScratch directory. The root cause of this issue is NuGet/Home#2793, so when that issue is fixed, the workaround here should be reevaluated.

Depending on the fix made in NuGet, we may want to remove the workaround in this repo. Alternatively, we may want to keep this behavior and also remove the NuGetScratch directory in the Windows images to reduce the size of the Docker images, similar to the removal of the apt-get caches.
