Fix wrong VRAM size calculation on old drivers without GET_FBINFO ioctl.
The linebytes is a byte number of width so it should be
(linebytes * height), not (width * linebytes).
XXX: I'm not sure where WSDISPLAYIO_GET_FBINFO implementation was discussed
     but I wonder if we should use proper ifdef or macro to share this
     third party Xorg driver with OpenBSD...
No need to handle colormap ioctls if cmsize == 0 even in WSFB_CI case.
Add kludge to use luna68k 4/8bpp framebuffers as a monochrome server.
The idea is taken from mlterm-fb --depth option implementation.
This change should not affect other framebuffer types.
Tested on 4bpp on LUNA and 1bpp/8bpp on LUNA-II.
