Zbigniew Jędrzejewski-Szmek 929f52632b man: move examples out of sd_journal_get_fd into separate files
man/.dir-locals is to keep indentation under control.

This makes it much easier to compile and run those examples, c.f. #7578.

v2:
- copy more of .dir-locals.el from the root to man/.dir-locals.el
  (I though emacs would inherit from the one in the parent dir, but
   it seems it just uses its own broken defaults, including
   indent-tabs-mode by default.)
