History
Steve Baker 0d0f7f8075 Rename existing BLS entry with the new machine-id 
This change replaces the call to grub2-switch-to-blscfg with a file
rename to update it to the actual machine-id.

grub2-switch-to-blscfg has issues in some build environments:
- When the build host is EFI boot, it assumes the image is, and
  fails when config file /etc/grub2-efi.cfg is missing
- With recent cento9 images and a fedora build host it fails with:
  grub2-probe: error: cannot find a device for / (is /dev mounted?)

                 before running bin/disk-image-create. This URL should point to
                 the directory containing the ``7/8/8-stream`` directories.
