Revert "gh-87079: Warn on unintended signal wakeup fd override in `asyncio` (#96807)" (#96898)

This reverts commit 05878106989c6f5b9dd35a6c15a21bee59312827.
Reason: This broke buildbots (some warnings added by that commit are turned to errors in the SSL buildbot).
Repro:  ./python Lib/test/ssltests.py
