Don't set OCF_LineConstruct if the object's definition only has C4D_EnergyHolder

set as LineConnect

This fixes the linekit displaying an error message when attempting to connect
an already started line to an object that has `LineConnect=C4D_EnergyHolder`,
as it does not support any line connection types and that flag isn't set for
line-related purposes.
