vulkan/wsi: Improve the DRI3 error message
This commit improves the message by telling them that they could probably
enable DRI3. More importantly, it includes a little heuristic to check
to see if we're running on AMD or NVIDIA's proprietary X11 drivers and,
if we are, doesn't emit the warning. This way, users with both a discrete
card and Intel graphics don't get the warning when they're just running
on the discrete card.
