osdep: add wait.h compat macros

Man page for WCOREDUMP says:

  WCOREDUMP(wstatus) returns true if the child produced a core dump.
  This macro should be employed only if WIFSIGNALED returned true.

  This  macro  is  not  specified  in POSIX.1-2001 and is not
  available on some UNIX implementations (e.g., AIX, SunOS).  Therefore,
  enclose its use inside #ifdef WCOREDUMP ... #endif.

Let's do exactly this.
