Karin is crazy for Sasuke. She wouldn't give her and Sasuke's child to another girl and make Sasuke marry that girl too. I mean if you were impregnated by a man you're so crazy for, would you give your child to him and make him marry another girl. I think Sakura is definitely the "biological mother" (wouldn't want someone go and say of course she's the mother even if she didn't give birth to her). Something just went wrong, might be the machine, the DNA sources, or the operator of the machine. But I think Sakura really is the Biological mother.

And if she's not then let it be. I'm more concerned for Boruto's future. Sarada got some real action and the Son of the MC of the first Naruto series is at konoha probably doing the same things as Naruto did in the past.
