Fix dependencies in vulkan pipeline test

The srcStageMask field in the subpass dependency was not strict
enough. This can cause that the incoming subpasses, that try to copy
samples from this subpass, may try to read content that may not be
 written yet.

Affects:

dEQP-VK.pipeline.multisample.min_sample_shading.min_*

Components: Vulkan

VK-GL-CTS issue: 1185

Change-Id: Ide5e3d2a709e8fe26d23ada1d20bf2eb27beffd8
