bind: seq.Transact requires interface descriptor.

Browse Source 
seq.Transact is called when Go calls a method of a foreign object
that implements a Go interface. Currently, we assume that the foreign
object has an instance method that can conduct the message routing,
so the object id and the method code is sufficient for transact.

Passing the interface descriptor (e.g.  go.testpkg.I) however allows
the bind internal to use non-instance methods to implement the routing.
