vf_scale: remove rounding of sizes to 2 with 4:2:0

libswscale doesn't seem to require this (anymore?), and libavfiltert's
vf_scale doesn't do it either. Moreover, this wasn't done for most other
subsampled formats, not even very old ones. So just remove it.

(It'd be quite easy to align on chroma boundaries with all pixel
formats, though.)
