[IMP] runbot: use a config file to simplify args

When starting an odoo instance with Docker, a very long command line is
computed and appears in the logs.

With this commit, an .odoorc configuration file is written ind the build
dir and mounted in the Docker container.

Previously, the runbot .odoorc/.openerprc file was mounted to share some
parameters. Now, if that file exsists, its content is merged with build
.odoorc.
