bsc: Sync osmo-{bsc,stp}.cfg with docker-playground.git

It appears some changes were made only to the files in
docker-playground.git, but not here.  This means that running
tests locally produced unexpected results.

We must always ensure that the tests run both without and with
docker, which means making sure the configs are all maintained!
