unit: add new test rilmodem-cs

This commit adds a new style of build-time/unit test to
rilmodem.  These tests setup a dummy server socket and
attach a gril instance to it.  This allows rilmodem
call-settings atom functions to be tested directly,
validating request parcels received by the server-side,
and callbacks that happen in response to canned responses
sent by the server-side.
