Applied to master with the following changes:

    [Thomas:
     - drop "runtime" on the depends on BR2_TARGET_GRUB2 since we now have
       a build-time dependency on it
     - explicitly copy the files installed by mender-grubenv in
       MENDER_GRUBENV_INSTALL_IMAGES_CMDS instead of blindly copying
       everything that is in $(TARGET_DIR)/boot/EFI]

Thanks!
