Fix modifier tests - Add Invalidate memory before host read.

After performing copyImagetoBuffer buffers no invalidation was given
before reading from host. Add the invalidate operation for buffer
before reading.

Components: Vulkan
VK-GL-CTS Issue: 3929

Affected tests:
dEQP-VK.transform_feedback.simple.*
