fftools/ffmpeg_filter: skip autoscale for hardware format

Browse Source 
This fix failure:
ffmpeg -hwaccel cuda -hwaccel_output_format cuda \
  -i The_Beauty_of_Earth-1.mp4 \
  -vf scale_cuda=2880:1440 \
  -c:v hevc_nvenc \
  -pix_fmt cuda \
  -b:v 8M -c:a copy \
  -y test_scale.mp4

> Reconfiguring filter graph because hwaccel changed
> Impossible to convert between the formats supported by the filter
> 'Parsed_scale_cuda_0' and the filter 'auto_scale_0'.
> Error reinitializing filters!
