New test case for core.efi file check needed by grub and shim upgrade…

… (New) (canonical#890)

If a device (x86 or arm with ebbr) uses grub and shim in classic image, we need to make sure grub and shim can be updated correctly when user tries to install a newer grub or shim deb package.

In some instances, the core.efi file was not present, creating problems on devices requiring it for subsequent updates to grub or shim, especially in the context of SecureBoot-enabled devices.

* Add a test case for core.efi file check needed by grub and shim upgrade

* Add the certification status and fix a typo

Fix OEMQA-2967
