Touch up XDG, add rootless links

Touch up a number of formating issues for XDG_RUNTIME_DIRS in a number
of man pages.  Make use of the XDG_CONFIG_HOME environment variable
in a rootless environment if available, or set it if not.

Also added a number of links to the Rootless Podman config page and
added the location of the auth.json files to that doc.
