systemc: Change how the timing of binding ports works.

In the Accellera implementation, interfaces are bound to ports
immediately if no ports have been bound, and otherwise saves them for
later along with the ports. The existing implementation would save
all interface and port bindings to finalize at the end of elaboration.

This seems like pointless complexity, but it's necessary to get the
output to match in the tests.
