Fix ill signal befavior of SIGCHLD in exec_ifconfig().

For some reason signal(SIGCHLD, SIG_IGN) was set *and* tries to wait
child process which always fails because SIGCHLD is never
delivered. Due to this "ifconfig up" fails when switching to watchdog
master. Fix is, before calling fork(), do "signal(SIGCHLD,
SIG_DFL)". See "[pgpool-general: 3310] Watchdog - ifconfig up failed."
for more details.
