[OE-core] [fido] [dizzy] Please port gummiboot install fix to fido and dizzy branches

[Chatre, Reinette]

Hi Joshua and Armin,

We are seeing installation failures as a result of gummiboot entries not being installed correctly. This is already fixed in master with the commit below. It applies cleanly to fido and dizzy branches since apart from this patch the file being changed has exactly the same git history there as master. Could you please port this fix to the fido and dizzy branches?

    init-install-efi.sh: fix gummiboot entry installation
    
    After selecting the "install" gummiboot option of a Live image we are
    seeing boot failure resulting from the gummiboot entries not being
    installed correctly. This seems to be a problem in this init-install-efi.sh
    script where it incorrectly installs the gummiboot entries into the root
    filesystem, not the boot partition. We fix it by installing the entries in
    the boot partition.
