stp: Support testing multi-home SCTP features with IPv4+IPv6
The IP addr module parameter is split now, IPA module has its own set of configurable addresses, and M3UA its own. Moreover, in M3UA the single address is transformed to be an array of addresses, to support multi-homing with both IPv4 and IPv6 addresses. Related: SYS#4915 Change-Id: Ib1925ed1df5cea3fa66f28b5625532d454a2c338
