gh-123085: Fix issue in inferred caller when resources package has no source.
From importlib_resources 6.4.3 (python/importlib_resourcesGH-314).
(cherry picked from commit a53812df12)
Fix the importlib.resources.as_file() context manager to remove the
temporary file if destroyed late during Python finalization: keep a
local reference to the os.remove() function. Patch by Victor Stinner.
