[oe] [PATCH 2/2] grub: allow menu.lst to be overridden using GRUB_CONFIG_PACKAGE.

[Michael Smith]

If GRUB_CONFIG_PACKAGE is set, don't ship menu.lst with grub. Instead,
RRECOMMEND the config package. This allows overlays to override menu.lst
in a separate package, rather than copying the whole grub package into
the overlay.
