Mark storage buffer as readonly

Since the test only reads it, mark the buffer as readonly. Without the
qualifier the test is invalid on implementations that don't support
vertexPipelineStoresAndAtomics.

Components: Vulkan
Affects: dEQP-VK.memory.pipeline_barrier.host_write_storage_buffer.*
         dEQP-VK.memory.pipeline_barrier.all.*
