efi/libstub: add some missing EFI prototypes
Define the correct prototypes for the load_image, start_image and unload_image boot service pointers so we can call them from the EFI zboot code. Also add some prototypes related to installation and deinstallation of protocols in to the EFI protocol database, including some definitions related to device paths.
