    Ensure we use just machine name for the host flag.
    
    DocImpact: Windows and Linux return different things for a call to
    socket.gethostname() (either FQDN or not). This method normalizes
    the output to make running mixed environments easier.
    
    The big goal here is to not changing the current default behaviour,
    whilst allowing deployments to do something different without
    having to set a customized flag on every machine. Therefore, the
    default value for the new hostname_length flag is "system", which
    will do whatever was happening before. If you want FQDNs, then you
    should change that flag to "full".
    
    Resolves bug 1055503.
