tmpfiles: allow to specify basename only: systemd-tmpfiles <program.conf>
Allow passing of basename only, instead of the absolute path; letting systemd-tmpfiles perform a path lookup for the proper fragment path in the config directories. This allows distributions to call: systemd-tmpfiles <program.conf> on upgrade of a package, with respecting the possibly overriden (or even masked) tmpfile.
