sd-bus: make strict asan shut up
    
    asan doesn't like it if we use strndup() (i.e. a string function) on a
    non-NULL terminated buffer (i.e. something that isn't really a string).
    
    Let's hence use memdup_suffix0() instead of strndup(), which is more
    appropriate for binary data that is to become a string.
