nir/lower_tex: Fix minor error in YUV color conversion matrix
The matrix used for YCbCr to RGB is listed in:
https://en.wikipedia.org/wiki/YCbCr
There was an error in converting the offsets from integers to unorm
values: 0.0625=16/256 should be 16.0/255,and 0.5=128.0/256 should be
128.0/255. With this fix, the CSC result is bit aligned with wikipedia's
conversion result and FFMPeg's result.
