Bug fix for mandos-client: Run the network hook, not the directory.

* plugins.d/mandos-client.d (set_cloexec_flag): Removed.
  (run_network_hooks): Do not set O_CLOEXEC on "hookdir_fd".
                       Instead, open hook to new "hook_fd" and simply
                       close(hookdir_fd) before fexecve().
