config: update CONFIG_LSM defaults (bsc#1205603).
    
    CONFIG_LSM determines what the default order of LSM usage is.  The
    default order is set based on whether AppArmor or SELinux is preferred
    in the config (we still prefer AppArmor).  The default set has changed
    over time and we haven't updated it, leading to things like bpf LSMs
    not working out of the box.
    
    This change just updates CONFIG_LSM to what the default would be now.
