gbproxy_vty: Fix NRI overlap behaviour to match osmo-bsc 

The MSC-pooling chapter in OsmoBSC mentions that overlapping NRI ranges will
warn if configured though the VTY interface, but fail when started with
such a config.

The manual for OsmoGbProxy promises a similar behaviour, this patch implements
it.
