e2e: do not use --tls argument in TestDialStdio

If the environment is not setup for tls (i.e. `$HOME/.docker/ca.pem` doesn't
exist) then this will exit with an error instead of allowing the test to
complete.

Since we just wanted to test that the `dial-stdio` was called with the same set
of options as the initial invocation just drop it, the other args already in
place serve the purpose well enough.
