summary:

[3.9] bpo-39481: Fix duplicate SimpleQueue type in test_genericalias.py (GH-22619) (#22624)

There are two different `SimpleQueue` types imported (from `multiprocessing.queues` and `queue`) in `Lib/test/test_genericalias.py`, the second one shadowing the first one, making the first one not actually tested. Fix by using different names.

Automerge-Triggered-By: @gvanrossum.
(cherry picked from commit b2c0a43699bd9023a69e3fa554f5488a2e17e278)
