RubyLB: ::first-line style should not be applied to all rubies
Sub-LineBreakers always referred to InlineItems for ::first-line
incorrectly because the constructor for them don't have an
InlineBreakToken.
This CL fixes it by passing the parent LineBreaker through
SetInputRange(), then PrepareNextLine() updates items_data_.
