Ramiro Polla 44bfe0da61 swscale/range_convert: fix truncation bias in range conversion
384fe39623 introduced a regression in the
range conversion offset calculation, resulting in a slight green tint
in full-range RGB to YUV conversions of grayscale values.

The offset being calculated was not taking into consideration a bias
needed for correctly rounding the result from the multiplication stage,
leading to a truncated value.

Fixes issue #11646.
