Only call setrlimit on linux

This MR works around failures seen on python3 on macos when calling setrlimit from a few scripts - the patch is to just only call those functions on linux.

I've gone ahead and rebased your branch as only fast-forward merges are allowed. When the pipeline succeeds, I'll go ahead and merge this in.

Hmm, not sure why it's failing right at the beginning with RPC errors but it's definitely unrelated to any changes you've made. I'll have to investigate to see if other forks also exhibit this behavior, but this looks fine otherwise.

@adam-mercer thought it might be related to the git repo being too large, with large files/blobs not properly stored with git-lfs, so the git checkout fails. This may be an issue with my fork, do other people see that error?
