kernel-config: Drop FB

In Linux 6.6 DRM_FBDEV_EMULATION no longer depends on FB, so we no
longer need to select FB (tested in a QEMU VM).

But if DRM is selected, we must select both DRM_FBDEV_EMULATION and
FRAMEBUFFER_CONSOLE or we'll see only blank screen. And now
FRAMEBUFFER_CONSOLE is not selected by default, be warned!!
