[aws-c-event-stream] Fix test_package memory leak

[jeremy-coulon]

Summary

Changes to recipe: aws-c-event-stream/*

Motivation

When trying to build aws-c-event-stream with ASan, I found a memory leak in test_package.

Details

Here is ASan report:

The memory is being released right away by the process termination anyway, but does not hurt to handle explicitly either.
