"[BEAM-4752] Add support for newer dill dependency"

Thanks, LGTM. I don't quite understand how the change breaks the SDK
harness though:
```
DataflowRuntimeException: Dataflow pipeline failed. State: FAILED, Error:
java.util.concurrent.ExecutionException: java.lang.RuntimeException: Error
received from SDK harness for instruction -83: Traceback (most recent call
last):

> Affects Versions: 2.4.0
> Environment: CentOS Linux release 7.4.1708
> Python 2.7.13

> I'm seeing the following error (stack trace below). I looked at the module
> structure of the {{dill}} library, and it does not have a {{dill}} submodule
> (although it *does* have a {{_dill}} submodule). I think the correct way to
> reference {{Pickler}} is simply {{dill.Pickler.}}
> {noformat}
> Traceback (most recent call last):
> File "script/beam_run_model.py", line 29, in <module>
> import apache_beam as beam

> Oddly, I have successfully used Beam 2.4.0 in the past with this version of
> Dill. ¯_(ツ)_/¯
