This commit adds a new kernel selftest to verify RTNLGRP_IPV4_MCADDR and RTNLGRP_IPV6_MCADDR notifications. The test works by adding and removing a dummy interface and then confirming that the system correctly receives join and removal notifications for the 224.0.0.1 and ff02::1 multicast addresses.

The test relies on the iproute2 version to be 6.13+.

Thanks for the test. Could you please add it to another (perhaps a new?) test? rtnetlink is the main configuration interface for networking, if we add all test cases that relate to it to a single file it will quickly become huge.
