Import Debian changes 1.0.23-2

tinc (1.0.23-2) unstable; urgency=low

  * Use if-statements instead of && in shell scripts. Closes: #731279
    The && operator does not clear the error status, and if the next statement
    in a shell script does not change the error status it would cause the
    script to prematurely exit. Thanks to Peter Reinholdtsen for spotting it.
  * Use absolute path to tincd in the if-post-down script.
