a.out: restore CMAGIC 



Part of UAPI and the on-disk format:
this means that it's not a magic number per magic-number.rst,
and it's best to leave it untouched to avoid breaking userspace
and suffer the same fate as a.out in general

Fixes: 53c2bd67 ("a.out: remove define-only CMAGIC, previously magic number")
