Remove SetFixedContainerSizeDelta from LayerPositionConstraintUnittest

Remove SetFixedContainerSizeDelta from LayerPositionConstraintUnittest

This function just wrapped simple logic and we can explicitly
call SetViewportBoundsDelta on the correct layer instead. This
is similar to https://codereview.chromium.org/2839533002 which
removed FixedContainerSizeDelta.
