FIX: Create configuration file from scratch

We've used to copy the .conf file from /debian/odoo.conf and modified it along the way to our needs. This could trigger issues and cornercases. Since Odoo 11.0 this breaks the default installation script.
There where two options:
1) Create sed commands to find the doubles and remove them - which would have issues with the regex expressions and special characters such as "/".
2) Create a new configuration file from scratch and fill it with our own data

Obviously, I went for option 2.
