[kwinglutils] Skip ShaderManager::selfTest for NVIDIA Quadro hardware

Browse source 
Summary:
The self test fails with NVDIDA 370.23 or newer on Quadro hardware.
Most likely there is a bug in our code as the same things work later on.
But without the hardware we are not able to reproduce and investigate
properly. Given that all we currently can do is to skip the self test.

We encourage users to investigate this properly and to help us to
identify the root issue, so that we can fix it.
