secruity: Fix CVE-2021-44228 mitigation

[StoneLabs]

Using rolling logs previously prevented the CVE-2021-44228 mitigation from working.
This commit forbids rolling logs if required to prevent CVE-2021-44228.

This can be considered a hotfix.

See #1189

Should be good now.

This is a great fix at this point. Someday I want to add a sub command to https://github.com/itzg/mc-image-helper to modify the application log4j config and insert the rolling log config.
