saslauthd update for etch

[anarcat]

We need to upgrade our installed saslauthd configuration with the following:

mkdir /var/spool/postfix/var mkdir /var/spool/postfix/var/run mkdir /var/spool/postfix/var/run/saslauthd chown -R root:sasl /var/spool/postfix/var/

/etc/alternc/templates/default/saslauthd:

OPTIONS="-r -m /var/spool/postfix/var/run/saslauthd -O localhost -c"

(instead of PARAMS)

(In [1954]) fix saslauthd config for etch, partial fix. See #1069

(In [1955]) fix ownership of saslauthd directory. Closes: #1069

[anarcat]

(In [1956]) use dpkg-statoverride instead of hardcoding config, because it will be replaced on saslauthd restarts. See: #1069. Closes: #684
