Subject: [PATCH] Convert to ISO 639-2/B for menu language

According to HDMI specification 1.4b, the Bibliographic codes of
ISO/FDIS 639-2 shall be used.
So add the logic to convert terminology codes to Bibliographic codes.

Test: see the 3 alphabets as a parameter of CEC command (<Set Manu
Language>) and check that they were replaced by ISO 639-2/B
