[pgpool-committers: 7304] pgpool: Delete any pre-existing watchdog command socket file at startup

[Muhammad Usama]

Delete any pre-existing watchdog command socket file at startup

Abnormal termination of Pgpool leaves behind the dangling socket files
and prevent Pgpool-II from starting up.
The solution is to delete any pre-existing watchdog command socket
file before binding a watchdog command socket.
