Fix TCS negative test

Fix TCS negative test

One of three tests that are checking incorrectly sized tessellation
control output array was actually correct. This is fixed by changing
array size to value that is small then layout declaration. Remaining
two tests check if compilation fails when value is greater then
layout declaration.
