gtpie_{encaps,encaps2}(): RAI is a fixe 6-byte length field, not 8 bytes

Browse Source 
gtpie_decaps() always had this right, but the encapsulation functions
treated it as 8-byte fixed length IE.

I hope we had a chance to convert all of this to the normal libosmogsm
tlv_parser one day.  This would have one description table for all TLV
types which then is used from encoder and decoder.
