This update for postfix fixes the following issues:

- Setting the security file permissions to "paranoid" could have caused
postfix to hang (bsc#1120757)

- postfix-files contained an incorrect path to postfix-ldap.so which resulted in an error
when running postfix set-permissions (bsc#bsc#1120110)
