MGCP_Test: do not use module parameter mp_test_ip (statsd)

The module parameter mp_test_ip was added with the following commit:
Change-Id I61e23e264bc85eb36d07431c7839fb445c110947

There is already mp_local_ipv4, which has the same function, so we
should remove mp_test_ip again and use mp_local_ipv4 to set up the
receiving of statsd information.
