[Piglit] [PATCH] generated builtin_uniform: Fix dimensions of cs tests

[Jordan Justen]

Previously we created a 16 x 16 texture. But, the generated tests
require a variable width based on the number of sub-test-cases. The
tests also only need a texture with a height of 1.

On Nvidia, this allows 211 more tests to pass.
