GNU-EFI had no provision for calling __init_array[] and __fini_array[] functions

the __init_array and __fini_array symbols with shorter names because the GNU-EFI
default in lib\ctors.S defines empty arrays which will cause efi_main to freeze.
GPT fdisk on EFI needs these because g++ uses __init_array to create static objects:
it doesn't use any .ctors section for some reason. We also add the __preinit_array[]
which seems to be unused. The symbols below are used in initfini.c with _call_init.
