[Piglit] [PATCH] arb_enhanced_layouts: fix shader GLSL version requirement

[Iago Toral Quiroga]

The test declares that only GLSL 1.40 is required, but then shaders
use version 4.20, leading to execution failures if the platform does
not support 4.20. Just require GLSL 1.40 in the shaders too, since
that is sufficient and consistent with other similar tests.
