lnwallet: add delivery scripts as a param to CreateCloseProposal+ CompleteCooperativeClose

Browse Source 
This commit modifies the methods that transition the state of the
channel into an active closing state. With the new commitment design,
the delivery scripts are no longer pre-committed to the initial funding
messages. Instead, the scripts are sent at the instant that either side
decides to shutdown within the Shutdown message.
