Skip Shader self test for Mesa >= 17

Browse source 
Summary:
We are getting reports about the shader self test failing in a false
positive way on Mesa 17. We already have such false positve results
for NVIDIA quadro and went with disabling the self test.

Most likely our self test has a problem or the rendering of the first
frame has a problem. But disabling compositing because our rendering of
the first frame is broken, is too much.

Let's better be pro user here and disable the shader self test till we
fixed the root problem.

BUG: 376801
FIXED-IN: 5.10.4

Test Plan: It compiles.
