It turns out that both UBO and intBitsToFloat() are supported in OpenGL ES 3.0[1][2], enable them so that NNEDI3 prescaler can be used in a wider range of backends. Also fixes some implicit int-to-float conversions so that the shader actually compiles on GLES. Tested on Linux desktop (nvidia 358.16) with "es" sub-option.
