2/2] Fix language selection and navigation bar (closes bug #36055)

The language selection drop-down was not working anymore after the
rework of the navigation bar because the ul#nav was over the
form#langsel and prevented clicks on the select widget.

Also fixes the navigation bar in RTL mode, which was forgotten during
the navigation bar fixes previously.
