The main reason: as Ryze you want to max CDR as early as possible - FH gives 20% which maxes your CDR with masteries and rank 5 Q, while IBG gives you 10%. Trust me that 10% CDR difference MATTERS A LOT.

The second reason - Ryze typically builds some damage items (Seraph's, RoA, Void Staff) which means he can only use 1 armor item and 1 MR item (unless against full AD). filling your armor item slot with IBG means you'll lack significant defence againsts physical damage as IBG gives much less armor than FH, while also not providing FH's passive. ADCs will melt through you, and you won't even deal that much more dmg than if you bought FH (30 AP and 100 mana. wow).
