Delete legacy config lines. They have been deleted in osmo-msc.git's
example config files in [1] and [2] almost a year ago.
When running locally, osmo-msc refuses to start with these lines. The
ttcn3-msc-test dir has its own osmo-msc.cfg file, so it works there
without this patch.
$ osmo-msc
There is no such command.
