Because I don't think Daeric Armor is looked at with good eyes. Also, Dragons Armor is made out of Dragon parts, and since the Dovahkiin is the only one able to slay a dragon, he is also the only one able to loot the dragon.

And the even of Skyrim happens 200 years after the Oblivion Crisis. If they brought something to Skyrim, it's likely sold or decaied now.
