vf_scale: conditionally override chroma position
For yuv420p, the chroma position is unilaterally overriden, even if ffmpeg's command-line explicitly set it. To fix this, override only if the value is the default one. Regression since 1515bfb3. Signed-off-by: Michael Niedermayer <michael@niedermayer.cc>
