glsl: make sure that interpolateAt arguments are variables
In the case of a constant, it might have been propagated through and
variable_referenced() returns NULL. Error out in that case.
Fixes 3 dEQP tests:
dEQP-GLES31.functional.shaders.multisample_interpolation.interpolate_at_sample.negative.interpolate_constant
dEQP-GLES31.functional.shaders.multisample_interpolation.interpolate_at_centroid.negative.interpolate_constant
dEQP-GLES31.functional.shaders.multisample_interpolation.interpolate_at_offset.negative.interpolate_constant
