* util/grub-mkconfig.in: Stop setting GRUB_VIDEO_BACKEND. Make it

Browse source 
available as a user override instead.  Replace the gfxterm backend
check with a check that ${GRUB_PREFIX}/video.lst is non-empty.
* util/grub.d/00_header.in (load_video): New generated function.
Call it before loading gfxterm rather than loading
${GRUB_VIDEO_BACKEND}.
* util/grub.d/10_linux.in (linux_entry): Call load_video.
* util/grub.d/30_os-prober.in (osx_entry): Likewise.
* docs/grub.texi (Simple configuration): Document
GRUB_VIDEO_BACKEND.

After @command{grub-install} has been run, the available video drivers are
listed in @file{/boot/grub/video.lst}.
@item GRUB_GFXMODE
Set the resolution used on the @samp{gfxterm} graphical terminal. Note that
you can only use modes which your graphics card supports via VESA BIOS
