[pgpool-committers: 3373] pgpool: SIGUSR1 signal handler should be installed before watchdog init

[Muhammad Usama]

SIGUSR1 signal handler should be installed before watchdog initialization.

Since there can be a case where a failover request from other watchdog nodes
arrive at the same time when the watchdog has just been initialized,
and if we wait any longer to install a SIGUSR1 signal handler, it can
result in a potential crash
