avcodec/msrledec: implement vertical offset in 4-bit RLE
The delta escape (2) is supposed to work the same in 4-bit RLE as in
8-bit RLE. This is documented in the MSDN Bitmap Compression page:
https://msdn.microsoft.com/en-us/library/windows/desktop/dd183383(v=vs.85).aspx
The unchecked modification of line is safe, since the loop condition
(line >= 0) will check it before any pixel data is written.
Fixes ticket #5153 (output now matches ImageMagick for the provided sample).
