We should consistently use the same name for protocol GUIDs as defined in the UEFI specification. Not adhering to this rule has led to duplicate definitions for the EFI_LOADED_IMAGE_PROTOCOL_GUID. Adjust misnamed protocol GUIDs. Adjust the text for the graphics output protocol in the output of the `efidebug dh` command. Signed-off-by: Heinrich Schuchardt <xypron.glpk@gmx.de>
