[pgpool-committers: 8510] pgpool: Prevent hang in terminate_all_childrens().

[Tatsuo Ishii]

Prevent hang in terminate_all_childrens().

waitpid() was used in the function without WNOHANG was being set.
This could cause hang in waitpic().
Also fix typo. Rename terminate_all_childrens to terminate_all_children.
