Subject: [PATCH] [init] Remove -addrmantest command line arg

-addrmantest is only used in `p2p_node_network_limited.py` test to
test if the node self-advertises a hard-coded local address
(which wouldn't be advertised in the tests because it's unroutable
without the test-only code path) to check pruning-related services
are correct in that addr.

Remove -addrmantest because the self advertisement happens because
of hard coded test path logic, and expected services are nominal
due to how easily the test-only code could diverge from mainnet
logic. It's also being used only in 1 test.
