From: Changqing Li <***@windriver.com>

Currently, yocto doc refer link http://www.tin.org/bin/man.cgi?
section=8&topic=update-rc.d. as man page of update-rc.d, but lastest
debian udpate-rc.d have big difference with ours, they need insserv
and all the initscripts support LSB comment header.

change to new link which is more similar to ours.
