GLES2: Ensure extension checks for texture2DLod

In canvas.glsl and scene.glsl, we were using texel2DFetch from stdlib.glsl,
which uses texture2DLod. In both cases, the stdlib.glsl include came before
the define of texture2DLod.

Might fix issues for drivers that don't support GL_EXT_shader_texture_lod.
