libobs: Fix tex.Load lookup (needs int3, not int2)

libobs' shader language is basically HLSL, and tex.Load uses an int3 for
2D textures, with texture mipmap index for the last component.  This bug
bypassed testing because the front-end automatically switches to OpenGL
if D3D11 initialization fails, and when converted to GLSL, works fine
because texelFetch only requires two components.  This also means
there's a bug in GLSL shader conversion code, because it's essentially
ignoring the third component when it shouldn't be.
