[sheepdog] [PATCH stable-0.9 3/4] deb: enable dh_systemd and provide a Debian-specific service file.

[Hitoshi Mitake]

From: Alexander Guy <alexander at andern.org>

The existing Debian sysvinit scripts are using different
environment variable names for configuration than those
present in the upstream systemd service file (e.g. DAEMON_ARGS).
This naming difference breaks sheepdog on Debian installs that
are using sysvinit and then migrate to systemd.

This patch provides a simple fix for the current issue, until
the time unification of variable names is desired/worked on.
