Server bug fix: Include CAP_SETGID so it does not run as root

* debian/mandos.postinst (configure): If old version was 1.7.4-1 or
  1.7.4-1~bpo8+1, fix situation where clients.pickle file is owned by
  root.
* mandos (main): Print debug info about setuid() and setgid()
* mandos.service ([Service]/CapabilityBoundingSet): Add "CAP_KILL
  CAP_SETGID"; the latter is needed for setgid() to be allowed.
