Adjust `--platform` tests for changes in docker engine 

These tests started failing on recent versions of the engine because the error string changed,
and due to a regression, the status code for one endpoint changed from a 400 to a 500.

On Docker 18.03:

The `docker build` case properly returns a 400, and "invalid platform" as error string;

```bash
docker build --platform=foobar -<<EOF
FROM busybox
EOF

Sending build context to Docker daemon  2.048kB
Error response from daemon: invalid platform: invalid platform os "foobar"
```

```

The `docker pull --platform=foobar hello-world:latest` case incorrectly returns a 500

On Docker 18.09;

```bash
docker build --platform=foobar -<<EOF
FROM busybox
EOF

Error response from daemon: "foobar": unknown operating system or architecture: invalid argument
```

Which incorrectly returns a 500 status;
