[Piglit] [PATCH] Remove #version from variable indexing shader tests.

[Stuart Abercrombie]

The idea is to ultimately remove explicit #version directives from all
.shader_test files, so we can just rely on GLSL >=, and then the ES
analog, allowing these tests to run on GL or GLES -- what Paul Berry
outlined a while back, basically.

This patch is confined to the variable indexing tests.  It removes
#version outputting from

tests/spec/glsl-1.10/variable-index-read.sh
tests/spec/glsl-1.10/variable-index-write.sh

and the files generated for 1.10/1.20 from these scripts.  I've
included the script modification below.

The follow-up was intended to be removal of #version from other
.shader_test files, and other regularization like what I sent in
before.

Since other work is being done for GLES I don't know if this is still
a reasonable way forward.  Thoughts?
