    modules: usa default value of I if LOGLEVEL is undefined
    
    This way external scripts (like pbuilder-satisfydepends-apt is) can use
    the log.*() functions without setting LOGLEVEL (which would imply
    parsing pbuilderrc and the comman flag) and have a chance of actually
    print something.
    
    Note that by choice the default value is used only in case of unset
    variable, and not also in case of empty value.
