chgrp tests started to fail in the CI

[sylvestre]

    test_chgrp::basic_succeeds
    test_chgrp::test_permission_denied
    test_chgrp::test_subdir_permission_denied

Maybe a change in the CI configuration ?

I am trying something here

[sylvestre]

Looks like a weird conf issue:

run: /target/x86_64-unknown-linux-gnu/debug/coreutils chgrp -R 121 dir
thread 'test_chgrp::test_permission_denied' panicked at 'assertion failed: `(left == right)`

The issue seems to be on the github side:

run: /usr/bin/whoami
resultdebug(whoami).stdout = 
resultdebug(whoami).stderr = /usr/bin/whoami: cannot find name for user ID 1001
