Duplicate unhash_blockpos code to legacy.lua

Browse Source 
Duplicating that small piece of code seems like a better idea than
putting the undo-forceloading code back into util.lua. This way, it is
easier to remember to remove that unneccesary code after a couple of
months / years, when people have transitioned. This also means we can
make changes to the code in util.lua without breaking old code.
