You would have to get a male Pokemon in Aron's egg group, which is Monster, that learns both of those attacks in some way. Then breed it with a female Aron/Lairon/Aggron.
Unfortunately, and correct me if I'm wrong, I don't believe that is possible. In the quick search I did, I couldn't find any Monster group Pokemon that learns both of those moves. Since only the male passes on egg moves, it isn't possible to breed a Head Smash female Aron and then breed it with a male Dragon Rush Pokemon to get both moves on Aron.
