INN 2.6.4 release candidate

[Marco d'Itri]

Sorry, I forgot that this patch or something to the same effect is 
needed to make systemd notifications (and future socket activation) 
work.
The reason is that systemd will only accept notifications from the
child process it spawned, so we need innd to be exec'ed by rc.news.

Without this patch inn will be stopped after one minute with messages 
like:

Jan 10 01:10:26 erode systemd[1]: inn2.service: Got notification message from PID 23629, but reception only permitted for main PID which is currently not known
Jan 10 01:11:23 erode systemd[1]: inn2.service: Failed with result 'protocol'.
Jan 10 01:11:23 erode systemd[1]: Failed to start InterNetNews.

ciao,
Marco
