Ports in shadow nodes are opened by the translator starting routine now.

Before, netfs_S_dir_lookup used to open the ports in shadow,
nodes. This could cause conflicts with the flags required by
the translator starting up on the node. Now the port is opened
only based on the flags requested by the translator being
launched.
