i915g: add dma-buf support to i915_drm_buffer_get_handle
The implementation of i915_drm_buffer_get_handle now handles DRM_API_HANDLE_TYPE_FD in the same way that intel_winsys_import_handle does, by calling drm_intel_bo_gem_create_from_prime. Tested by successfully running Chrome's ozone_demo [1] with the ozone-gbm backend on an Intel Pineview M machine. Without this change it fails while trying to create a DMA-BUF.
