yhirose 49708a18b2 Enable ASAN detect_stack_use_after_return for #2431 repro ...

The bug is a textbook stack-use-after-return: a stack-local struct gaicb
is destroyed when getaddrinfo_with_timeout returns after gai_cancel()
yields EAI_NOTCANCELED, then the still-live resolver worker thread writes
back into the freed frame. ASAN's detect_stack_use_after_return is the
direct detector for exactly this pattern -- enabling it lets the failure
surface as a clear ASAN diagnostic during the test run instead of as an
orphan-process hang at job teardown.
