lib70x: Fix Sharp_CopyLine()

As part of the copyline function, we have to fill in the "extra"
head/tailroom on either end.  Headroom was done correctly, but tailroom
was not, instead overwriting the head room of of the next row.

This probably has no visible effect on the image, but it was incorrect.
