Use offset to avoid lookups

In systemd vtable entries, each of property and method callbacks have a
version of the callback that takes an "offset" parameter.  This allows
passing a userdata pointer at an offset from the original userdata
pointer.  This allows us to optimize, and not have a O(n) lookup on our
vectors, and allows us to directly dereference the correct callback,
without needing to mess around with trying to find the callback we're
looking for.
