Map Quechua languages to closest ones with tags

OpenType only officially maps four ISO 639 codes to Quechua languages,
but prior versions of HarfBuzz also mapped qu to 'QUZ '. Because qu is a
macrolanguage, the mapping now applies to all individual Quechua
languages. OpenType calls 'QUZ ' "Quechua", but it really corresponds to
Cusco Quechua, so the individual Quechua languages should not all
necessarily be mapped to it.
