Adjust the key frame placement condition
The commit removed a limit on key frame detection, which caused a big
drop in all metric measurements for standard HD clip such as _mobcal.
This single change helps two standard HD clips by a huge amount, which
help the overall std-hd set by 2.4% (glb psnr), 0.9% (avg_psnr), 2.1%
(vpxssim).
In the result page:

represent the encoding test results and std-hd set prior and after this
commit respectively.
