[libgpiod][PATCH 3/3] bindings: python: tests: don't use the same chip from different threads

[Bartosz Golaszewski <brgl@bgdev.pl>]

From: Bartosz Golaszewski <bartosz.golaszewski@linaro.org>

There are no thread-safety guarantees in libgpiod. Let's not reuse the
chip object created in one thread to generate info events in another but
use a global request function instead.
