    core: never consider failure when reading drop-ins fatal
    
    drop-ins don't carry the main configuration of a unit, hence read them
    if we can't, complain if we cannot, but don't fail.

    conf-parser: never consider it an error if we cannot load a drop-in file because it is missing
    
    After all, we want to be able to boot with /etc empty one day...
