[gnome-continuous-yocto/gnomeostree-3.28-rocko: 6992/8267] initramfs-framework: include install-efi module in recipe for installation

[Emmanuele Bassi <ebassi src gnome org>]

commit 8b960914ac6193c2146eb1bb39fc9ec5c0008404
Author: Ng, Wei Tee <wei tee ng intel com>
Date:   Sun Jul 23 16:51:56 2017 -0700

    initramfs-framework: include install-efi module in recipe for installation
    
    Utilized the existing init-install-efi.sh script and renamed it to
    install-efi.sh to manage the installation process of images in
    initramfs-framework model. This script will be executed when
    "install" option is being chosen in the grub menu and install
    the image on the target platform. A new install-efi module is
    being added in the recipe to handle the installation process
    using initramfs-framework.
