"k5srvutil change" failed on a RHEL-5 beta machine, where the tail
command, in an apparent effort to be more POSIX compliant, no longer
recognizes the "+<number>" option.  This patch fixes the problem by
making use of awk's NR variable, thereby obviating the use of tail.
(Note that the POSIX tail's "-n" option is not portable, and in
particular is not accepted on Solaris),
