vo_opengl: fix precision loss of fruit dithering matrix
With default setting, the matrix for fruit dithering requires 12 bits precision (values from 0/4096 to 4095/4096). But 16-bit float provides only 10 bits. In addition, when `dither-size-fruit=8` is set, 16 bits are required from the texture format. Fix this by attempting to use 16 bit integer texture first. This is still not precise, but should be better than using a half float.
