vgabios: Set cursor shape fixes
The "cursor scaling" mode is determined by the first bit of the
video_ctl bda value, not the modeset_ctl value. Also, on a
set_scan_lines() call, the shape should be set to lines-3/lines-2 and
the shape must be set after char_height has been updated.
The existing cursor shape code matches the legacy "lgpl vgabios", but
the behavior doesn't match bios documentation nor observations with an
ati vga bios.
