[efi] Allow DEBUG=efi_wrap to be used independently of a loaded image

Allow temporary debugging code to call efi_wrap_systab() to obtain a
pointer to the wrapper EFI system table.  This can then be used to
e.g. forcibly overwrite the boot services table pointer used by an
already loaded and running UEFI driver, in order to trace calls made
by that driver.
