Fix T47724: VSE crops video if horizontal resolution isn't divisible by 8

This is a bit annoying, but FFmpeg can't deal with unaligned arrays in some
cases. There seems to be an easy workaround with using SWS_ACCURATE_RND flag
which should be harmless since we don't really scaling frames, but only
using sws_scale to change color space.

Additionally, this is what VLC is also using.
