The rules for Steel Hellkite say any nonland permanent with converted mana cost X gets destroyed if I deal combat damage this turn. The second ruling states "It doesn't matter who controlled those permanents at the time Steel Hellkite dealt combat damage, or if those permanents were even on the battlefield at that time."
Does this mean if I make the X cost 2/2, all my opponent's 2/2 cards, even in his library are destroyed?
The key word here is "permanent", which in the game of Magic essentially means "a card or token that's on the battlefield". Cards in someone's library are never counted as being "permanents".
MTG Comprehensive Rules, 110.1:
A permanent is a card or token on the battlefield. A permanent remains on the battlefield indefinitely. A card or token becomes a permanent as it enters the battlefield and it stops being a permanent as it's moved to another zone by an effect or rule.
Also note that "converted mana cost" has nothing to do with being a 2/2 creature. There are quite a number of things that cost 2 mana that are also 2/2 creatures, but not all 2/2 creatures "have a converted mana cost of 2", by any means!
