elfcore.h : Fix UML build breakage

Commit a65e7bfc

 broke the UML build with
the following error -

  In file included from fs/proc/kcore.c:17:
  include/linux/elfcore.h: In function 'elf_core_copy_task_regs':
  include/linux/elfcore.h:129: error: implicit declaration of function 'task_pt_regs'

Fix this by restoring the previous behavior of returning 0 for all arches
like UML that don't define task_pt_regs.
