Make vertex shader boilerplate to set gl_Position

If we don't generate any fragment from the previous stages, the
fragment shader might not be run. Hence invalid results for
GL45-CTS.shader_image_load_store.multiple-uniforms in the fragment
stage.

Components: OpenGL
Affects: GL45-CTS.shader_image_load_store.multiple-uniforms
VK-GL-CTS issue: 30
