Supplied rulesets: Simplify Barracks effects by BuildingFlag
With User Building flag support from #45832 we can simplify, and I think improve performance (it's quicker to check one effect with BuildingFlag requirement, than three effects with Building requirements), of Barracks effects on supplied rulesets.
This weakens AI as long as it suffers from #46617
