[OE-core] [PATCH 2/3] bootimg/grub-efi.bbclass: allow using a different class for EFI images

[Stefan Stanacar]

Abstract away some names so one can select using EFI_PROVIDER a different
class than grub-efi for populating live images, basically allowing the use
of a different bootloader than grub-efi.
