Add missing memory barrier to the image load/store tests

The test issues multiple glDispatchCompute with the same dst
but misses a glMemoryBarrier call.
This violates section 7.11.2 of the GLES specification.

Components: OpenGL

Affects: KHR-GL*.robust.robust_buffer_access_behavior.image_load_store

VK-GL-CTS issue: 992
