plugin aesgcm: use 12 bytes Initialisation Vector:
SàT was using 16 bytes IV when sending files withr AES-GCM, due to ChatSecure being only
compatible with that. Monal, an other iOS client is only compatible with 12 bytes IV, and
ChatSecure has fixed its code to also handle 12 bytes IV, so there is not reason anymore
to use 16 bytes, and SàT now uses 12 bytes.
