test: Add explicit onion bind to p2p_permissions

When the bind option is replaced in the bitcoin.conf, bitcoind will
attempd to bind to the default tor listening port. If another bitcoind
is running that is already bound to that port, the bind will fail which,
since bitcoin#22729, causes the test to fail.
