evas gl - fix yuv smooth rendering 

i found that we are not setting u and v to be smooth (linear
interpolate) for yuv reendering, even when asked. they remain at a
default "nearest". this enables linear for u and v always, meaning
even when smooth is off, we still interpolate u and v (not y), and
even when at 1:1 with no scaling u and v get interpolation for better
quality.

@fix!
