cube: Fix new validation error
As of Vulkan-ValidationLayers commit 2872f4a, the layers now check that
image layouts specified in descriptors match the current image layout
state. LAYOUT_GENERAL is not a wildcard for this matching.
Change the image layouts for the combined image sampler descriptors
from LAYOUT_GENERAL to LAYOUT_SHADER_READ_ONLY_OPTIMAL.
