We're currently using GenericPendingReceiver::interface_name()
when forwarding the bind request to the system connector, which
is returning a reference string. However, the |interfae_name_|
is resetted in GenericPendingReceiver::PassPipe(), which is
invoked in the same bind request. This results in system connector
getting corrupted interface name.

So make a copy of the interface name, and use it for the bind
request.

Bug: 146448872
Test: Verify no crash when CastAudioOutputStream uses ServiceConnector
      to request MultiroomManager interface.
