Test gltf texture without renderer.
Summary: Change the cow gltf loading test to validate the texture values and not to validate the renderer output because it has an unstable pixel. Also a couple of lints. Reviewed By: patricklabatut Differential Revision: D29131260 fbshipit-source-id: 5e11f066a2a638588aacb09776cc842173ef669f
