Description of problem:
A custom named.conf contains include "/etc/rndc.key"
rndc.conf prior to the U8 update also contained include "/etc/rndc.key"
The U8 update changes rndc.conf to include a hardcoded key statement instead of
/etc/rndc.key.
This results in rndc nolonger being able to authenticate itself to named.

Version-Release number of selected component (if applicable):
9.2.4-14_EL3

How reproducible:
Consistently

Steps to Reproduce:
1. Existing named.conf must contain include "/etc/rndc.key"
2. Existing /etc/rndc.conf must be unmodified (so it will be updated during the
upgrade)
3. Upgrade from 9.2.4-7_EL3 to 9.2.4-14_EL3
4. service named status
  
Actual results:
rndc: connection to remote host closed
This may indicate that the remote server is using an older version of 
the command protocol, this host is not authorized to connect,
or the key is invalid.

Expected results:
rndc status output

Additional info:
Checking a clean install of bind-9.2.4_14_EL3 on a pristine machine that's never
seen bind before also produces a non-working config. That is one where the
default named.conf includes /etc/rndc.key but /etc/rndc.conf hardcodes a
different key.
