adriconf expects i915_dri.so while i965_dri.so present

Created by: Ristovski

Seems like another corner-case - either i915_dri.so or i965_dri.so might be present based on the hardware. The kernel driver on the other hand will always be named i915.

I have tested symlinking i915_dri.so to i965_dri.so and can confirm this fixes the issue.
