bit_depth_template: use av_clip_uint8 over crop_tab.
This fixes some global out of array reads and wrong cliping. No speed difference meassurable under clang on i5 also all important code paths on all important platforms should use SIMD. Found-by: Mateusz "j00ru" Jurczyk and Gynvael Coldwind Signed-off-by: Michael Niedermayer <michaelni@gmx.at>
