Fix T87068 EEVEE: Moire effect with particle hair and subsurface

This artifact was already present in previous version but was hidden
by the faulty SSS scale.

The issue comes from the translucence using the geometric normal
(computed using fragment shader derivative) leading to poor precision at
depth discontinuity.

Replacing using the same geometric normal reconstruction as the ambient
occlusion pass removes most of the issue.
