More Heimdal 1.5.2 port problems

[Robert Simmons]

I've found another problem with the port.

kadmind and kdc both look for krb5.conf in /usr/local/etc, but
kpasswdd and kstash look for it in /etc.  This can be fixed with a
symlink, but I feel like that's not the best solution.  Ultimately,
all the heimdal utilities and daemons should be looking in the same
location for krb5.conf, correct?

I don't see any flags for kstash or kpasswdd to change where they look
for krb5.conf.

I'm going to go back and compile it from source again and see if there
is another configure flag that is missing from the port.
