Add missing barrier in synchronization tests
The *read_vertex_input* tests write to a storage
buffer in the vertex stage, which will later
be mapped by the host to read and verify the
results. Add a barrier before attemptig to read
the data from the host.
Components: Vulkan
Vk-GL-CTS issue: 266
Affected tests:
dEQP-VK.synchronization.op.single_queue.semaphore.*read_vertex_input*
