Bug 11057: Bootstrap theme: fix display of active language in language chooser

There is a problem with how an active single language is styled, making
the alignment look incorrect. This patch amends the markup and the CSS
to make it look better. This patch does not address the position of the
language menu.

To test you must have at least one additional single translation
installed. Apply the patch, refresh the page, and confirm that the
display of the active language is improved.

The selected language has not a padding, contrary to others.
Not perfect but it fixes the descripted behavior.
