For Fedora and RHEL use system-wide crypto policy for mod_ssl
    
    Drop the SSLProtocol directive for Fedora and RHEL systems. mod_ssl
    will use crypto policies for the set of protocols.
    
    For Debian systems configure a similar set of protocols for what
    was previously configured, but do it in a different way. Rather than
    iterating the allowed protocols just include the ones not allowed.
