    Don't immediately restart tracker-extract on SIGSYS
    
    If the seccomp sandbox doesn't allow a necessary syscall, restarting
    tracker-extract is likely to make it fail again at the same syscall.
    In this case we don't want tracker-extract to restart in a tight loop,
    leaving a new core dump every time.
