I know that this is a late response, but the varying opinions really made me want to put up my thoughts here and I didn't find an immediate better place to do it. It's also 3:42 in the morning, so please have patience if my wall of text makes little sense.
We need to establish a few basic things before I can continue.
The first is that geth can develop a conscious worship. The heretics worship the reapers, to be 'given the future' as Legion describes their motives. It's noticed in how Saren is described like a prophet-figure in his relation to the geth. He tells Shepard that the geth worship Sovereign, and that the reaper is even offended by this.
The second thing is that the geth
can consider icons and symbolism important. The use of the altar on Feros confirms this. You can even see the geth kneeling in front of it.
Worshipping an altar is an extreme use of icons. The true geth declined Sovereign's offer to help him in order to pursue their own future, making themselves the enemies of the reapers, as Legion explains.
Shepard reasons the same way in Mass Effect 1. Saren makes it clear that by making itself useful, humanity could endure and be spared rather than end up as enemies of the reapers. Despite the appearent invincibility of the reapers, despite the odds, he chooses to fight rather than to put his race(and the galaxy) at the mercy of the reapers.
Technically speaking,
Shepard recieves the same offer from Saren as the geth recieved from Sovereign. Continued existance, technology in return for obediance. Both declined. The difference is that Shepard took this a step further and destroyed Sovereign.
"You killed their god. Your code is superior." Not only does this sentence prove that they hold Shepard in extremely high regard (expressed in geth words), it also marks Shepard as what we could call the 'slayer of an enemy deity'.
Legion acknowledges that 'The Old Machines' could give them the future, but that the geth have chosen to build their own future. This is a principle, not a mathematical calculation as you would expect from a machine.
My theory in short; The true geth community either have or are reaching a conclusion that Shepard is the icon for their principles of existance. They identify themselves with Shepard from the choices that he has made in regards to the reapers and aspire to be more like him since "his code is superior". That is the reason as to why they would iconify him and wear his armor. Wether this is consciously or not is impossible to say.
Why the geth would make use of altars/icons/symbols at all is a question that lies way further back in the game than the moment Legion decided to pick up a piece of N7 armor.
I want to quote Legion a final time. This is what Legion says when you speak to him after you destroy the Collector base;
"An interesting choice Shepard-Commander. Your species was offered everything the geth aspire to. True unity, understanding, transcendence. You rejected it. You even refused to use the Old Machines' gifts to achieve it on your species' own terms. You are more like us than we thought."
".. than we thought."
