[packages] tinc: Version bump to 1.0.23

With pleasure we announce the release of tinc version 1.0.23. Here is a
summary of the changes:

 * Start authentication immediately on outgoing connections (useful for sslh).

 * Fixed segfault when Name = $HOST but $HOST is not set.

 * Updated the build system and the documentation.

 * Clean up child processes left over from Proxy = exec.

This version of tinc is compatible with 1.0pre8, 1.0 and later, but not
with earlier version of tinc.

Here is a summary of the changes in version 1.0.22:

 * Fixed the combination of Mode = router and DeviceType = tap.

 * The $NAME variable is now set in subnet-up/down scripts.

 * Tinc now gives an error when unknown options are given on the command line.

 * Tinc now correctly handles a space between a short command line option and
   an optional argument.
