ELN: Disable SHA-1 by default using CentOS patches
    
    ELN should ideally be ahead of CentOS and RHEL with policy changes, but
    due to time constraints was not. Fix that by bringing the current CentOS
    9 / RHEL 9 state of SHA-1 disabling to ELN.
    
    Due to differences in their lifecycles, Fedora's packages will stay at
    allowing SHA-1 by default for now. There is a plan to gradually catch up
    to the ELN state over the next few releases.
