Changed options of ffmpeg in conan:

- updated options to include new options added in upstream
- enabled swresample to allow audio resampling via ffmpeg instead of
custom methods
- disabled all components other than those that are needed for vcmi
- changed required version to allow newer ffmpeg versions
- added lzma as explicit dependency (used by innoextract)
