Fix bug that watchdog status goes down even when only one of trusted servers get unpingable

When there are two hosts in trusted_servers, pings to each hosts are execued in forked
procceses in each threads. This bug is caused by wrong result handling that receives
other thread's ping result. Resolve by using waitpid() instead of wait().
