[Piglit] [PATCH 2/7] gles-3.00: Fix various errors in varying-struct-centroid test

[Ian Romanick]

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

This test has obviously been broken since 2d69390, which I alegedly
reviewed.  The name of the vertex shader input was changed from vertex
to piglit_vertex, but none of the references in the shader were changed.

Also, the default float precision qualifier was missing in the fragment
shader. *shock*
