Filebeat on Centos 8 doesn't seem to properly parse /var/log/secure

Hi!

I see that the module is tested with various environments: https://github.com/elastic/beats/tree/13a54632caa9c69f1126733addbfa2e69a34f2d4/filebeat/module/system/auth/test

Would you like to open a Github issue and let the team know about your case and ask to evaluate if this should be supported too?

Thanks!
