mandos-ctl: Update Emacs lisp test runner code

* mandos-ctl: Update Emacs lisp after-save-hook test runner to use
              file-local-name if available (i.e. Emacs 26), or to use
              file-remote-p if not (Emacs 25).  Either should be more
              general than the tramp-* functions were.  Also use
              process-file-shell-command instead of shell-command,
              which enables the use of the less intrusive
              display-buffer-in-side-window action function argument
              to display-buffer.  This stops the takeover of buffers
              (and/or disappearance of windows) when saving.
