Speed up docker start (#647)

Starting the docker container is hampered due to setting `chown -R www-data:www-data /var/www/html/` on every start, causing it to traverse the entire directory which in our use case is very slow. This PR instead changes it to set permissions as part of the build process.

Sidenote: Is `LE_EMAIL` supposed to be used in addition to `ADMIN_EMAIL`?
