Install wordpress using composer in a specific language

I'm using composer to automatically deploy wordpress on a ubuntu-server. Additionally, I need to install the german language pack. I learned that there are some guys who create composer-packages from the wordpress.org files. Using the following composer.json I get wordpress with german language pack: 

{
    "repositories": [{
        "type": "composer",
        "url": "https://wp-languages.github.io"
    }],
    "require": {
        "johnpbloch/wordpress": "4.6",
        "koodimonni-language/core-de_de": "*"
    },
    "extra": {
        "wordpress-install-dir": "wp",
        "dropin-paths": {
            "wp/wp-content/languages": ["vendor:koodimonni-language"],
            "wp/wp-content/languages/plugins/": ["vendor:koodimonni-plugin-language"],
            "wp/wp-content/languages/themes/": ["vendor:koodimonni-theme-language"]
        }
    }
}

The problem is, that wordpress itself is still in english. Is it possible to set it automatically to german, so that I don't have to do this manually for every site in the adminpanel?

The current WP versions expose interface for this and store locale in WPLANG option. Depending on your tools you could set it up during your spin up process (for example with WP CLI).

Older version used WPLANG constant in wp-config.php. I think it should still work on a fresh install (if you don't have option set up) so you could include it in whatever process you use to write wp-config.php.
