This finally removes the last Android hack. Both Chromium and Android end up needing this thing (Chromium needs it for WebCrypto but currently uses the EVP_AEAD version and Android needs it by way of wpa_supplicant). On the Android side, the alternative is we finish upstream's NEED_INTERNAL_AES_WRAP patch, but then it just uses its own key-wrap implementation. This seems a little silly, considering we have a version of key-wrap under a different API anyway. It also doesn't make much sense to leave the EVP_AEAD API around if we don't want people to use it and Chromium's the only consumer. Remove it and I'll switch Chromium to the new---er, old--- APIs next roll.
