emc-test-suite: Disable bball using glx for xwayland
With the layer upgrade there seem to be some build problems and we do not really need this variant currently.
Dear all, On Thursday, 4th September 2025, we will test the new disaster recovery environment. A disaster recovery test will take place between 4:00 PM and 6:00 PM CEST. Please refrain from making any changes, as they will be lost. Once testing is complete, the production environment will be restored. Thank you for your understanding.
