Can you show me the full postinst generated with your patched version?
AFAICT, neither dh_installinit nor dh_installsystem should pass those
file names as a single argument.  When I tested locally, the shell
snippet seemed to correctly pass each file as separate arguments.

The override support that the patch adds is that
/etc/tmpfiles.d/foo.conf can now override /usr/lib/tmpfiles.d/foo.conf
(previously, it could not).

There was nothing to support "foo.conf" overriding "bar.conf" (or
"00rsyslog.conf" overriding "var.conf").

For your concrete issue, you will have to use one of Michael's
recommendations listed in:

  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=894510#37, OR

  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=894510#42

Sorry, but that is the best I can offer you without diverting for the
recommendations from the systemd maintainers.
