The test contained bugs which made it fail on multiple platforms.
After mapping SSBO, access the data with GLuint instead of GLboolean.
The elements in the SSBO are 4 machine units, even though the SSB
talks about bools.
A bvec2 declared after bool in the SSB has alignment requirements.
The test asserts that a shader written result is zero. In this case
it needs to initialize the result buffer to non-zero in order to
prove that the shader put the zero there.
