[Piglit] [PATCH 3/4] varying-struct-centroid: Convert to new piglit_build_simple_program().

[Eric Anholt]

I'm not intentionally singling this test out (which would have tried
to continue if a shader stage failed to compile), it's just the first
thing I looked at when I was going to crib code for a new GLES test,
and decided to go work on new util functions instead.
