[vulkan] Hook up fisheye rendering in the output pass

Browse source 
It turns out that my laptop doesn't do multiview properly (or I've
misconfigured something, later), but the biggest issue I had on my
desktop seems to be that I had the push constants wrong: fov in aspect,
time in fov, and I had degrees instead of radians (half angle) anyway.
