[PATCH] systemd: fix PN-container package splitting

[Adrian Freihofer <adrian.freihofer@gmail.com>]

From: Adrian Freihofer <adrian.freihofer@scs.ch>

- Fix package splitting for services installed with
  systemd-container. Some files have been installed with systemd
  package instead of systemd-container package. (*.service,
  *.socket, *.html...)
- Split journal-upload, journal-remote, journal-gatewayd into
  separate packages. These services are not strictly related to
  nspawn containers. Remote logging is now possible without
  installing all the container stuff.
- systemd-container package rdepends on the new packages to
  maintain 100% backwards compatibility. But nspawn does not
  really depend on them. rrecommends would be fine as well.
