fixup! fsmonitor--daemon: use a cookie file to sync with file system

When flushing the FSMonitor data, we do not actually need to wait for a
cookie file. In the worst case, we will over-report a bit.

If we _do_ wait for a cookie file, in the worst case we cause a hang
because the FSMonitor daemon will wait and wait even though the `.git/`
directory might be gone already.
