Bug description:
In Fedora 43 test_group_no_follow_symlinks started failing with a peculiar failure for Python 3.14 and Python 3.13:

+ sysThe gid, which is asserted the line above, is in both cases the same (3), but the names don't match.
The tests calls _get_pw_name_or_skip_test, which calls pwd.getpwuid(uid).pw_name - which in return stopped giving the right result in our environment.

The cut contents of the two system files (you can check it for yourself spawning the fedora:rawhide container with podman run -rm -it fedora:rawhide /usr/bin/bash):
bash-5.2# head /etc/group
root:x:0:
sys:x:3:
adm:x:4:
bash-5.2# head /etc/passwd
root:x:0:0:Super User:/root:/bin/bash
bin:x:1:1:bin:/bin:/usr/bin/nologin
daemon:x:2:2:daemon:/sbin:/usr/bin/nologin
adm:x:3:4:adm:/var/adm:/usr/bin/nologin
I believe the test should use the other helper function prepared _get_gr_name_or_skip_test. It was probably an accidental copy-paste omission in the first place. I verified this will make the tests pass.
