Test has a shader with only one uniform which is not used. Test checks

Test test does not pass with GTX 660 running the Nvidia proprietary
driver for Linux version 319.32 because the uniform does not get the
location.
To my reading of the spec, glGetUniformLocation can return -1 for the
inactive explicit-located uniform. And even if it's inactive, no _other_
uniform can get that location.
