minor migration guide issue

[Zoltan Frombach]

In the migration guide located at 
http://www.freebsd.org/releases/5.3R/migration-guide.html under "5.2 Source 
Upgrades" under point 18 the following is missing:

rm /usr/sbin/nslookup /usr/sbin/nsupdate

(from UPDATING 20040925: " The following files have moved to /usr/bin, and 
should be removed from their old locations:  /usr/sbin/nslookup 
/usr/sbin/nsupdate")
