AVRO-2593: Ensure exfile is Always Defined
Fixes a bug where when a test fails the cleanup code tries to access a variable
that might not have been defined when the error occurred.

> Key: AVRO-2593
> URL: https://issues.apache.org/jira/browse/AVRO-2593
> Project: Apache Avro
> Issue Type: Bug
> Components: python

> Priority: Major
> Fix For: 1.9.2

>
> lang/py/test/test_tether_word_count.py is somewhat fragile. When it fails,
> the true failure is obscured by [a secondary
> error|https://github.com/apache/avro/blob/master/lang/py/test/test_tether_word_count.py#L210]
> because {{exfile}} is first defined on [line
> 179|https://github.com/apache/avro/blob/master/lang/py/test/test_tether_word_count.py#L179]
> and may not even exist in the {{finally}} block.
> I propose a significant refactor of this test to make the results clearer and
> to adhere to more idiomatic testing and python by:
> # Isolating the main test from its setup and teardown using standard setUp
> and tearDown.
> # Isolating the subprocess try/finally from the entire test setup/teardown.
> # Avoid having to manage multiple temporary files by running the entire test
> in a temporary directory.
