Revert "Evas 3D: Fix shadow map shader"

Summary:
This reverts commit 4af7a947a6fe1834d3fb5a8af3cd73196d237f74.
There is more convenient way remove noise in vector gl_Fragcolor at shadow_map
shader, because current decision lead to useless issue with shadow effect.
Need just add default initialize at the begining in shader file smth like that
gl_FragColor = vec4(1);
I suppose do that after this patch.
