Intel VAAPI DRI module is not symlinked into the right place
Context
VAAPI doesn't work with 18.08. The i965_drv_video.so driver is not found in the /usr/lib/x86.../dri module dir.
Description
The symlink that refers this path to the intel-vaapi-driver extension point is missing: https://github.com/flatpak/freedesktop-sdk-images/blob/1.6/org.freedesktop.Sdk.json.in#L2724
Acceptance Criteria
The symlink should exist:
