New versions of osmo-pcu support Neighbor Address Resolution over this
interface, and deprecated the old CTRL interface.
Let's use it by default while still keeping support for the old one for
a while to avoid breakage of existing deployments.
Tests run to validate:
* Old osmo-pcu still passes tests using CTRL interface
* New osmo-pcu (with new iface support) still passes tests using CTRL
interface
* New osmo-pcu (with new iface support) passes tests using new iface

Currently osmo-bts seems to be sending IPA RSL Connect ACK
unconditionally, even if the remote peer is not reachable.
