[Csync2] actions are incorrectly run on local host, possible problem with signal(SIGCHLD, SIG_IGN)

In server mode, csync2 forks and forgets per new connection.
So within the fork loop, the SIGCHLD signal must be restored.
I think something like:
	signal(SIGPIPE, SIG_DFL);
	signal(SIGCHLD, SIG_DFL);
must happen in the if(!fork()) { } to restore signal behaviour,
or at least just before the execve of the command.
