FlexRAN: make agent_id for identification purposes, discern from mod_id 

The agent_id is a uint64 consisting of: module ID (i.e. mod_id, the several
instances of OAI at once, 16 bit), the enb_id from the configuration file (32
bit) and the cell_id from the configuration file (16 bit).

The module ID is part of the agent ID but it is easier to have it directly in
the struct.
