Subject: [PATCH 200/220] grub-switch-to-blscfg: Update grub2 binary in ESP for
 OSTree systems

The grub2 EFI binary in the ESP isn't updated as a part of an OSTree update
transaction. So let's make the script to update this and also create a file
to indicate that the installed version has support for the blscfg module.
