[Buildroot] Building DirectFB kernel module

Hi Phil,

I don't think the DirectFB package is supposed to build the sh772x
kernel module. It's just there because the sh772x gfxdriver depends on
the kernel ioctl interface

So if you need buildroot to build another kernel module, you will have
to add another package.
You can take package/linux-fusion as an example. It builds/installs
the fusion kernel module for the directfb multi application mode.
