codecs: for IuUP, use AMR for codec matching

For finding usable codecs / matching codecs with remote call leg, use
AMR in place of IUFP.

On Iu, to the MGW we need to set the codec VND.3GPP.IUFP on the RAN
facing side. On the CN facing side, we indicate AMR instead, so that the
MGW decapsulates the IuUP into plain AMR RTP.
