pythongh-117649: Fix file descriptor leak in (expected) failing test case (python#117780)

colesbury · diegorusso · commit 5a6de66f216d · 2024-04-17T11:30:36.000+01:00
The test case is currently expected to fail in the free-threaded build.
However, it fails before it gets a chance to close the write end of
the pipe.
