pflocal: fix destruction of explicitely bound sockets

Sockets must have a weak reference on the address they're bound to so
that addr_unbind is properly called before addr_clean. For sockets that
are automatically bound, this weak reference is created in ensure_addr.
Do the same in sock_bind.

* pflocal/sock.c (sock_bind): Handle weak reference on addr.
