- update to 1.0.85:
* remove duplicate includes
* Fix blank documentation line in service file

- Some cleanup (bsc#1206639):
* removed patch setup-tgt-conf-d.patch, since it's upstream,
and having it caused duplicated include of user config
* renamed setup-tgt-conf-d.patch to
tgt-install-examples-in-documentation-dir.patch, to better
reflect what it does (since it no longer sets up tgt.conf.d)
* removed the sytemd source file we have, since we get
tgtd.service from upstream now (with a patch)
* added patch tgt-systemd-service-update.patch, to ensure
SUSE-specific changes are in the service file
* dropped tgt-include-sys-macros-for-major.patch (obsolete)
