[Piglit] [PATCH] shader_runner: Set uniform block bindings for multiple UBOs

[Chris Forbes]

glLinkProgram (re)sets all uniform block bindings to zero. If we want
to actually use multiple uniform blocks, we need to call
glUniformBlockBinding to specify which binding point goes with which
uniform block.
