libopenjpegenc: fix out-of-bounds reads when filling the edges

The calculation of width/height should round up, not round down to
prevent setting width or height to 0.

Also image->comps[compno].w is unsigned (at least in openjpeg2), so the
calculation could silently wrap around without the explicit cast to int.
