[FIX] Odoo 8.0-10.0: entrypoints: pass the pg parameters with CMD

When nothing is passed as argument to the docker container, the
entrypoint will receive the content of the CMD of the dockerfile. In
this case we have to pass the database configuration arguments, else
Odoo won't run correctly. This is the case when you run the command of
our documentation:

``` docker run -p 8069:8069 --name odoo --link db:db -t odoo ```

However, it should still be possible to run custom command (like `ls /`).
