Ava Chow 082779d606 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 #22729, causes the test to fail.

This failure can be avoided by explicitly binding the tor port when the
bind is removed.
