So, it is defined that:
Γλμυ = Γλμυ + δΓλμυ
This makes obvious to see that the variation of the connection, which is defined as a difference of 2 connections, is indeed a tensor.
Therefore we can express it as a sum of covariant derivatives.
δΓλμυ = ½gλν(-∇λδgμν + ∇μδgλν + ∇νδgλμ)
However, I do not know how to make this step. Help?
