MSC+BSC: add separate suites for AoIP: aoip_sms, aoip_debug

It would be nicer to select the network programs as scenarios, i.e.
independently from the specifics of tests that don't care whether a NITB or a
MSC+BSC is in place. See OS#2270.

For now have a separate script for BSC+MSC+HLR operation to be able to rapidly
get the binaries to work. We might even simply drop the NITB style, in which
case we don't need to make it configurable.
