[issue40014] os.getgrouplist() can fail on macOS if the user has more than 17 groups

Thanks for the PR, Victor, it does address the problem.  I went back and explicitly tested on macOS 10.14 and 10.13 by creating some more groups and adding the user to them and the same failure occurred there so this is not just a 10.15 issue.  Most likely this hasn't been an issue before is that 10.15 creates more groups for system services than the earlier versions did.  So the PR should be updated to remove the 10.15 (and 10.5!) references.
