Use 8-tap interp filter in temporal filtering

Used 8-tap interp filter in temporal filtering to achieve more accurate
motion search result. Using 8-tap sharp gave slight better result than
using 8-tap regular.

Speed 0 borg test showed that
        avg_psnr:  ovr_psnr:    ssim:
hdres:  -0.160      -0.157     -0.173
midres: -0.083      -0.061     -0.183
lowres: -0.077      -0.099     -0.204

Speed test didn't see noticeable encoder time changes.
