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.
