Issue description:
When deploying the attached test project to my Android device, the procedureale sky doesn't get rendered correctly, in spite of https://docs.godotengine.org/en/3.1/tutorials/misc/gles2_gles3_differences.html explicitly saying "[...] in GLES2 environments you can only set: Sky (including procedural sky) [...]"
GLES2: There's no gradient visible on the sky sphere; rather, when looking above the horizon, the sky gets rendered as uniform blue and when looking down it suddenly switches to being completely gray.
GLES3: The sky looks just blue, no matter where I look.
Steps to reproduce:
Deploy the attached test project to an Android device and see for yourself.
