[Piglit] [PATCH 2/2] arb_uniform_buffer_object: Add UBO from vs-struct-pad tests

From: Ian Romanick <ian.d.romanick at intel.com>

The vs-struct-pad and fs-struct-pad tests both fail on Mesa.  The UBOs
from those tests are added here to help narrow down the origin of the
problem.

This test passes on NVIDIA (304.64 on GTX 260).
