add_interface_variables() is supposed to add variables for the inputs of
the first shader stage linked into a program, and the outputs of the
last shader stage linked into a program.
From the ARB_program_interface_query specification:
"* PROGRAM_INPUT corresponds to the set of active input variables used by
the first shader stage of <program>. If <program> includes multiple
shader stages, input variables from any shader stage other than the
first will not be enumerated.
* PROGRAM_OUTPUT corresponds to the set of active output variables
(section 2.14.11) used by the last shader stage of <program>. If
<program> includes multiple shader stages, output variables from any
shader stage other than the last will not be enumerated."
Previously, we used build_stageref here, which walks over all linked
shaders in the program. This meant that internal varyings would be
visible. We don't actually need any of build_stageref's code: we
already explicitly skip packed varyings, handle modes, and the name
comparisons just do a fuzzy string comparison of name with itself.

Note: This patch appears to violate older OpenGL and OpenGLES specs.

The deqp
dEQP-GLES3.functional.shaders.linkage.varying.rules.differing_interpolation_2

OpenGLES 3.0. This patch simply removes the checking in all cases.
The OpenGLES 3.0 conformance test suite doesn't appear to require the
older ("must match") spec behavior.
For reference, here are the relavent spec citations:
The OpenGL 4.2 spec says: "the last active shader stage output
variables and fragment shader input variables of the same name must
match in type and qualification (other than out matching to in)"
The OpenGL 4.3 spec says: "interpolation qualification (e.g., flat)
and auxiliary qualification (e.g. centroid) may differ."
The OpenGLES GLSL 3.00.4 specification says: "The output of the
vertex shader and the input of the fragment shader form an
interface. For this interface, vertex shader output variables and
fragment shader input variables of the same name must match in type
and qualification (other than precision and out matching to in)."
The OpenGLES GLSL 3.10 Specification says: "interpolation
