Thomas Zimmermann 40faaf80c4 fbdev: Fix sys_imageblit() for arbitrary image widths ...

Commit 6f29e04938 ("fbdev: Improve performance of sys_imageblit()")
broke sys_imageblit() for image width that are not aligned to 8-bit
boundaries. Fix this by handling the trailing pixels on each line
separately. The performance improvements in the original commit do not
regress by this change.
