[pgpool-committers: 2395] pgpool: Restore SIGCHLD handler to its original after executing if_up/d

[Yugo Nagata]

Restore SIGCHLD handler to its original after executing if_up/down_cmd

Previously SIGCHLD was set to SIGIGN always after if_up/down_cmd.
This led to a incorrect error handling of ping or other commands
execution, and warning messages were output to log even when the
command exited successfully.
