Fix pgpool -m f stop" hang.
This is caused by unmanaged pgpool children remaining. This could
happen if multiple PostgreSQL are going down (or even starting pgpool,
without starting PostgreSQL can easily trigger this). Child calls
degenerate_backend_set() and it tries to aquire semaphore to write a
failover request. In this case the signal mask is set as well, thus
signals are never received. To fix this, kill pgpool children before
