Supporting CaC content 0.1.57

[omok314159]

We fail to compile xml files when we use our contents for CaC 0.1.57. So we need to fix several issues for supporting CaC 0.1.57.

Is this down to the control-file based approach that CaC is now taking upstream for some of the CIS RHEL profiles? If not, that approach is likely something that'll need considering too.

Hi there, by the way, I've been doing some work on the RHEL content upstream in CaC recently and I'm having a browse through this repo to see if there's any way I might be able to help with the goal of upstreaming the Rocky content too.
