[OE-core] [PATCH 1/5] grub-efi: replace anonymous function with static configuration

[dbaryshkov at gmail.com]

From: Dmitry Eremin-Solenikov <dmitry_eremin-solenikov at mentor.com>

Replace anonymous function setting GRUB_* variables with static
configuration, since grub-efi.bbclass will use fixed names for grub
bootloader.
