The mesh gives its names to the containers it declares. This one is started by
the test with `docker run` — nothing declared it, so nothing configured it, and
removing the workaround here was claiming a reach the change does not have.
The boundary is the right one: a container somebody runs by hand is not the
mesh's to configure. Reaching into every container on a machine, declared or
not, is what a resolver in resolv.conf would be for — and that remains the
case for wanting one.
The proof that names work inside containers is its own test, against a
container the mesh declared, and it passes.
