  signals: remove log in SIGCHLD handling

Avoid deadlock generated when a SIGCHLD (caused by the completion of a
process started through for example `exec`) handler tries to log
something to syslog while the actual process was writing at syslog.
Kudos to Javier Gallart from Sonoc for reporting the issue and testing
the fix.
