by laforgeRevert "hnbgw: osmo-hnbgw.cfg: Update file to make it similar to the one in docker-playground"
This reverts commit e9c6c7b97ee5b870212c54a08064acbde5670d5d which
breaks all of the test cases reliably. I'm surprised how it got
submitted in the first place, as it can never have worked. It uses
127.0.0.1:2905 on both the STP and the HNBGW side.
