avcodec/mpegvideo_enc: use 64bit multiplication in dct_quantize_trellis_c and dct_quantize_c
Fixes corruption with:
ffmpeg -t 1 -filter_complex "sine=f=21,showwaves=scale=cbrt:mode=line:colors=white:draw=full" -c:v mpeg2video -non_linear_quant 1 -qmin 1 -qmax 1 -cpuflags 0 out.mpg
or
ffmpeg -t 1 -filter_complex "sine=f=21,showwaves=scale=cbrt:mode=line:colors=white:draw=full" -c:v mpeg2video -non_linear_quant 1 -qmin 1 -qmax 1 -trellis 1 out.mpg
