Add a glMemoryBarrier between buffer write and read

The tests' behavior is like this:
1. Use transform feedback to write to one buffer
2. Set this buffer to texture, and then to image
3. glDispatchCompute -> use ImageLoad to read from the image
We have to add a glMemoryBarrier between step 1 and 3.

Affects:
KHR-GLES3*.core.texture_buffer.texture_buffer_operations_transform_feedback

Components: OpenGL
