    sys/_offsetof.h: pacify GCC 12's macro redefinition check
    
    GCC 12 has a strict definition of identity (all characters including
    whitespace must be identical) when comparing "redefined" macros. Make
    our definition exactly match the stddef.h that comes with GCC to fix
    test-includes of netlink/netlink_snl.h.  (Note: later versions of GCC
    are a bit more flexible and don't have this problem.)
