vo_gl: improve 10-bit YUV->RGB conversion accuracy slightly
Modify the YUV->RGB conversion matrix to take into account the
difference between the same color value being x/255 in a 8-bit texture
and x*256/65535 in a 16-bit texture (actually things are stored as
x*4/65535 for 10-bit color, but that can be ignored here). This 0.4 %
difference in the shader float value could make shades of gray in
10-bit (or generally more than 8 bit) YUV produce RGB values with
green slightly higher than red/blue.
