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.

            This option allows you to override the default shell

            command that the server will use to check if the client is
172
 
            still up.  Any output of the command will be ignored, only
173
 
            the exit code is checked:  If the exit code of the command
174

            a <option>checker</option> option to check for the

            The <replaceable>TIME</replaceable> is specified as a
339
 
            space-separated number of values, each of which is a
340
 
            number and a one-character suffix.  The suffix must be one
341
 
            of <quote>d</quote>, <quote>s</quote>, <quote>m</quote>,
342
 
            <quote>h</quote>, and <quote>w</quote> for days, seconds,
343
 
            minutes, hours, and weeks, respectively.  The values are
344
 
            added together to give the total time value, so all of
345
 
            <quote><literal>330s</literal></quote>,
346
 
            <quote><literal>110s 110s 110s</literal></quote>, and
347
 
            <quote><literal>5m 30s</literal></quote> will give a value
348
 
            of five minutes and thirty seconds.
 
348
            The <replaceable>TIME</replaceable> is specified as an RFC
 
349
            3339 duration; for example
 
350
            <quote><literal>P1Y2M3DT4H5M6S</literal></quote> meaning
 
351
            one year, two months, three days, four hours, five
 
352
            minutes, and six seconds.  Some values can be omitted, see
 
353
            RFC 3339 Appendix A for details.
