glcpp: Update tests for new #undef of built-in macro rules.

Ian recently changed the preprocessor to allow this in most GLSL
versions, but not GLSL ES 3.00+.  This patch converts the existing
test that expects a failure to a #version 300 es shader, and adds
a #version 110 shader to make sure that it's allowed.

Fixes 'make check'.
