We weren't handling the LUMINANCE_SNORM, LUMINANCE_ALPHA_SNORM and
INTENSITY_SNORM cases. Note that adding these cases here does not
require a driver to support rendering to these surface types. If
the driver can't do it we'll report an incomplete framebuffer.
NVIDIA doesn't support GL_EXT_texture_snorm but their driver
accepts these formats in glRenderBufferStorage().
