fix sit loading on shutdown

Description of problem:
According to the system logs, the last thing my non-NetworkManager controlled computer does before shutting down is load the sit IPv6 over IPv4 tunnel module.

Version-Release number of selected component (if applicable):
initscripts-9.20.1-1.fc14

How reproducible:
Always

Steps to Reproduce:
1. Review system logs from the previous system shutdown.
2.
3.
  
Actual results:
The final 4 lines logged are:

Nov 10 22:31:27 ejs-desktop kernel: IPv6 over IPv4 tunneling driver
Nov 10 22:31:27 ejs-desktop kernel: sit0: Disabled Privacy Extensions
Nov 10 22:31:28 ejs-desktop kernel: Kernel logging (proc) stopped.
Nov 10 22:31:28 ejs-desktop rsyslogd: [origin software="rsyslogd" swVersion="4.6.3" x-pid="8985" x-info="http://www.rsyslog.com"] exiting on signal 15.

Expected results:
Less IPv6 usage on system shutdown, saving 2 log lines.

Additional info:
"/sbin/ip link set sit0 down" loads the sit module if it isn't already loaded.
