zmq: Pass lambda to zmq's ZMQPublishRawBlockNotifier

Browse Source 
The lambda captures a reference to the chainman unique_ptr to retrieve
block data. An assert is added on the chainman to ensure that the lambda
is not used while the chainman is uninitialized.

This is done in preparation for the following commits where blockstorage
functions are made BlockManager methods.
