explicitly set do_fancy_downsampling to FALSE

Apparently, when settings dinfo.raw_data_in,
previous version jpeg automatically set dinfo.do_fancy_downsampling to FALSE. Newer versions (since 7) of media-libs/jpeg do not do that anymore and the program must do it explicitly (although I have not found any documentation to that effect).

Compile tested only, but a similar fix in mjpegtools (but output rather than input) works.
