ptal, strict patch - thanks for the comments

[Tom London]

Daniel, Ivan, thanks for the helpful comments.

Appears that ptal only needs 'server', so I changed to
'can_network_server_tcp(ptal_t)'.

I defined 'ptal_port_t' in network.te, and bound it to port 5703 in
network_contexts.

Hope this is better. Please correct....
