 close_others_do and   close_others_maxhint fields.

* process.c (EXEC_OPTION_CLOSE_OTHERS): removed.
  (rb_execarg_addopt): update the new fields, instead of options array.
  (check_exec_fds): take eargp as an argument.  update the
  close_others_maxhint field.
  (rb_execarg_fixup): follow the argument change of check_exec_fds.
  (rb_execarg_run_options): use the new fields.
