Fix mkfs btree item offset calculation

Browse Source 
mkfs was miscalculating the offset of the start of the free region in
the center of blocks as it populated blocks with items.  It was using
the length of the free region as its offset in the block.  To find
the offset of the end of the free region in the block it has to be
taken relative to the end of the item array.
