bpo-40014: Fix os.getgrouplist() (GH-19126)
Fix os.getgrouplist(): if getgrouplist() function fails because the
group list is too small, retry with a larger group list.
On failure, the glibc implementation of getgrouplist() sets ngroups
to the total number of groups. For other implementations, double the
group list size.
