Making X11DRV_DIB_SetDIBColorTable update DIB visible state

[Jukka Heinonen]

Colonize paints into DIB and after that changes the DIB colormap.
However, Wine failed to notice that updating colormap is an
operation that might alter the visible state of the DIB and
shows the DIB using wrong colors. The following patch fixes this.

Changelog: Changing DIB color table now updates the DIB visible state.
