Fix incorrect assumption for pipeline cache hit

The test incorrectly assumes that adding a pipeline creation flag bit
VK_PIPELINE_CREATE_ALLOW_DERIVATIVES_BIT to only one pipeline
still should cause a cache hit. Fixed the problem by adding the
VK_PIPELINE_CREATE_ALLOW_DERIVATIVES_BIT flag bit to both pipelines.

Affects:
dEQP-VK.pipeline.creation_feedback.compute_tests.compute_stage

Components: Vulkan
VK-GL-CTS issue: 2068
