child-cfg: Use separate method to get configured traffic selectors

Optionally with "dynamic" traffic selectors resolved.  A new method
is added for those cases where we actually want to select potentially
narrowed traffic selectors using a supplied list.  The latter now also
always logs details, while the former does not.
