WP_LANG_DIR defaults to wp-includes/languages when wp-content/languages doesnt exist

Currently WP_LANG_DIR defaults to wp-includes/languages/ when WP_CONTENT_DIR/langages/ doesnt exist
This is done for back-compat when languages used to be stored there.
Ideally this should default to the current-generation location unless (for some reason) the user has files in the old location and nothing in the new location.
