shadow-utils

Hi guys.
Old issue strikes back? On centos 10?
```
 -> $ mock something centos-stream-10 .... 
...
ERROR: Command failed:
 # useradd mockbuild -o -u 1000 -g 135 -N -d /builddir --prefix /devs/var/mock
```
past mentions are about incompatible/broken/different shadow-utils.
mock-6.6-1.el10_2
many thanks, L.
