mscsplit: add gsm_network backpointer to gsm_subscriber_connection

We want to be able to use a network backpointer without having to go through a
gsm_bts struct.

This commit adds the network pointer, the subsequent commit applies direct
access to the network structure from gsm_subscriber_connection.
