[Piglit] [PATCH] glsl-1.50: do not link interface-blocks-containing-unsized-arrays.geom

[Iago Toral Quiroga]

Linking means that we will validate in/out blocks between consumer and
producer stages. In this case it should fail because for geometry shaders
piglit will include a dummy vertex shader that does not have a matching
output block.

This has not been a problem until now because the linker was not detecting
this situation properly and did not produce the expected link error. I am
sending a patch to Mesa to fix this and once that lands this will start
to fail without this patch.
