grub-install doesn't notice that efibootmgr fails, reports success

[Karl-Philipp Richter]

Invoking

    sudo -i
    mount /dev/sdxY /mnt/bla
    cd /mnt/bla
    mount --bind /dev dev
    mount --bind /sys sys
    mount -t proc /proc proc
    mount /dev/sdxB /mnt/boot
    mount /dev/sdxE /mnt/boot/efi
    chroot .
    apt-get install grub-efi
    update-grub
    grub-install /dev/sdx

causes errors due to missing `efivars` with hint to run `modprobe efivars` and then prints `Installation finished. No errors reported.` (can't reproduce exactly right now, but it should be clear which message is meant). That is confusing! The final message should reflect whether errors have been reported or not.

this has been reimplemented, grub-install no longer calls efibootmgr.
