[libc++] Fix hang in counting_semaphore::try_acquire
Before this patch, `try_acquire` blocks instead of returning false.
This is because `__libcpp_thread_poll_with_backoff` interprets zero
as meaning infinite, causing `try_acquire` to wait indefinitely.
Thanks to Pablo Busse (pabusse) for the patch!
