child-cfg: Allow suppressing log messages when selecting traffic selectors

Although being already logged on level 2, these messages are usually just
confusing if they pop up randomly in the log when e.g. querying the configs
or installing traps.  So after this the log messages will only be logged when
actually proposing or selecting traffic selectors during IKE.
