main: Disable the Languages menu with one audio trackwip/hadess/disable-languages

Disable the languages menu if there's just a single audio track. This is
slightly cumbersome as we need to go and find the widgets themselves to
disable them, as there's no actions related to the menus, so nothing we
can disable by hand.

Closes: #102
