selftests: net: use ip commands instead of teamd in team rx_mode test

Replace teamd daemon usage with ip link commands for team device
setup. teamd -d daemonizes and returns to the shell before port
addition completes, creating a race: the test may create the macvlan
(and check for its address on a slave) before teamd has finished
adding ports. This makes the test inherently dependent on scheduling
timing.

Using ip commands makes port addition synchronous, removing the race
and making the test deterministic.
