jquery: Update sponsor line (commit 2016 live hack)

These two files were modified directly on the server on 21 Dec 2016,
but never committed back to Git, leading to the git clone at
`jquery-blogs:/var/www/blog.jquery.com/wp-content/themes/` being
in a dirty state.

This change effectively matches
jquery/jquery-wp-content@9b9edd507b73.
