avfilter/scale_eval: Reduce rounding error.
When force_original_aspect_ratio and force_divisible_by are both
used, dimensions are now rounded to the nearest allowed multiple of
force_divisible_by rather than first rounding to the nearest integer and
then rounding in a static direction. This results in less distortion of
the aspect ratio.

78676ee8f8 avfilter/scale_eval: remove redundant mathematical constants
Even though removed from vf_scale in 3b316f9f22, they were reintroduced
when scale.c, now scale_eval.c, was split off in 037bb4021c

e73688eff4 avfilter: rename scale.c,h to scale_eval
scale.c is too generic; scale_eval is more representative
