misc: Add an option exit/quit when the BSSGP is supposed to be destroyed

The PCU does not properly re-set the state when the connection to the
BTS is lost (and the SGSN potentially is re-started during that). This
results in the BSSGP BVCI > 1 remaining blocked and no data will be
accepted by the SGSN.

Add the '-e' option and exit the PCU when the BSSGP/NS are getting
destroyed.
