Add support for forcing EFI installation to the removable media path

Add support for forcing EFI installation to the removable media path

Add an extra option to grub-install "--force-extra-removable". On EFI
platforms, this will cause an extra copy of the grub-efi image to be
written to the appropriate removable media patch
/boot/efi/EFI/BOOT/BOOT$ARCH.EFI as well. This will help with broken
UEFI implementations where the firmware does not work when configured
with new boot paths.
