BSSGP_Emulation: usse alive-type for internal BVC created components 

Otherwise, during shutdown of all components we may end up in a
situation where the BVC is already killed and BSSGP Emulation receives
a packet which tries to forward to BVC and fails.

This can be seen quite a lot in PCU_Tests.TC_pcuif_suspend:
"""
PCU_Tests.ttcn:394 setverdict(pass): none -> pass
...
PCUIF_Components.ttcn:246 Stopping test component execution.
...
GPRS_Components.ttcn:222 Connection of port BSSGP[0] to TC_pcuif_suspend-BVCI1234(6):BSSGP_SP was closed unexpectedly by the peer.
