gsk: Upload textures in linear sRGB

We want to do compositing in a linear colorspace,
so convert textures to linear sRGB before uploading.

Currently, this causes images to come out dark, since
we don't have a way to tell the compositor that our
framebuffer is linear, so it assumes a gamma that we
don't provide.
