port_fwd: Split TCP and UDP cases for get_bound_ports()

Browse source 
Currently get_bound_ports() takes a parameter to determine if it scans for
UDP or TCP bound ports, but in fact there's almost nothing in common
between those two paths.  The parameter appears primarily to have been
a convenience for when we needed to invoke this function via NS_CALL().

Now that we don't need that, split it into separate TCP and UDP versions.
