org-open-file: Avoid make-process for Emacs 24 compatibility

* lisp/org.el (org-open-file): Select a pipe connection type with
process-connection-type rather than make-process, which isn't
available until Emacs 25.

This uses the alternative approach suggested by Eli Zaretskii in the
thread that led to 5db61eb0f (org.el: Avoid xdg-open silent failure,
2021-03-21): https://orgmode.org/list/83y2g96ta6.fsf@gnu.org
