Fix too dark rendering on the Monado runtime

Just like the Windows Mixed Reality runtime, we have to apply a sRGB
OETF to get visually correct-ish looking colors.
We plan to further investigate if it's really WMR and Monado being wrong
here, or if it's Oculus (which doesn't need this additional transform),
but there are some details to check.
