msrledec: use signed pixel_ptr in msrle_decode_pal4
This fixes segmentation faults, when pic->linesize[0] is negative. In that case 'line * pic->linesize[0] + pixel_ptr' is treated as unsigned and wraps around. This reverts commit 7d78a964. The problem was introduced in commit f7e1367f, which should obsolete that commit.
