tests/ranap_rab_ass: Test RAB-Ass.req with X.213 IPv4 address len=7 

It was found in the field that some peers sends an X.213 IP address
consisting of 7 bytes (1byte IDP/AFI, 2byte ICP, 4 byte IPv4 address) insetad
of 20 bytes. This was until recently failing in osmo-hnbgw due to
missing decoding functionalitit in osmo-iuh.git. Cover it here.
