Title:
  shim-signed package can not be configured on Lenovo Yoga C630 WOS

Bug description:
  Hello!

  Besides issue with shim itself described in Bug 1849863 I noticed that
  there is also issue with shim-signed package installation script.
  Attempt to install shim-signed on Lenovo Yoga C630 WOS cause following
  errors and left shim-signed package in unconfigured state, which will
  cause more issues later on (for instance update-manager will always
  try configure shim-signed on every upgrade).

  Installing for arm64-efi platform.
  grub-install: warning: Cannot set EFI variable Boot0000.
  grub-install: warning: efivarfs_set_variable: writing to fd 7 failed: Invalid argument.
