Make sure all dictionary descriptions are translated

Some dictionary extensions use 'en' as the language code of their
description.
The toolchain needs 'en-US' here to extract the extension name
as a translatable string.
As a result these names do not appear
localized in Pootle and then in the Extension Manager.

With this fix new pot files are generated in workdir/pot/dictionaries/
