i965: Set tiling on BOs imported with modifiers

We need this to ensure that GTT maps work on buffers we get from Vulkan
on the off chance that someone does a readpixels or something.  Soon, we
will be removing GTT maps from i965 entirely and this can be reverted.
None the less, it's needed for stable.
