Update to 8.2.13 and fix as per robertames@hotmail.com PR

Reminder for package maintainers of ircd-hybrid: ircd-hybrid now has
GnuTLS support as of version 8.2.13

Bug report from robertames@hotmail.com

When shutting down ircd-hybrid, a confusing error is displayed
stating the pid file does not exist:

/usr/local/etc/rc.d/ircd-hybrid stop

Stopping ircd_hybrid.
Waiting for PIDS: 14504.
rm: /var/run/ircd/ircd.pid: No such file or directory

This is because after ircd correctly cleans up it's pid file, the
rc script tries to delete the non existing file. In the rc script,
stop_postcmd is not needed.
