[FIX] t2d: add ssh key to authorized_keys

Since /home/odoo/.ssh is marked as a volume in the parent image, changes
to files in the directory during docker build are being lost when a new
container is created. Therefore the authorized_keys file is set directly
on the host and copied over to the container.

Closes #211.
