### Current Behavior

Error when invoking lambda if the `LAMBDA_DOCKER_FLAGS` is specified

### Expected Behavior

_No response_

### How are you starting LocalStack?

With a `docker run` command

### Steps To Reproduce

#### How are you starting localstack (e.g., `bin/localstack` command, arguments, or `docker-compose.yml`)
```shell
CONTAINER=$(docker run -d --rm \
        -v "$(pwd)":/hello \
        -v /var/run/docker.sock:/var/run/docker.sock \
        -e DEBUG=1 \
        -e DOCKER_HOST="$BITBUCKET_DOCKER_HOST_INTERNAL":2375 \
        -e LAMBDA_DOCKER_FLAGS="-e HELLO=hello" \     # Error cause!
        localstack/localstack:2.1.0)
```

#### Client commands (e.g., AWS SDK code snippet, or sequence of "awslocal" commands)
```shell
docker exec "$CONTAINER" awslocal lambda create-function --function-name testlambda --role arn:aws:iam::000000000000:role/DummyRole --runtime java11 --handler com.atlassian.lambda.demo.SNSEventLambdaHandler --zip-file fileb:///hello/dx-ref-java-lambda.jar --memory-size 1024 --timeout 20
docker exec "$CONTAINER" awslocal lambda publish-version --function-name testlambda
sleep 3

docker exec "$CONTAINER" awslocal lambda invoke --function-name testlambda --invocation-type RequestResponse out
```
In error message you will see the following:

```
which is caused by:
```python
if args.privileged is not None:
            LOG.warning(
                f"Overwriting Docker container privileged flag {privileged} with new value {args.privileged}"
            )
            privileged = True
```
in `localstack.utils.container_utils.container_client.Util.parse_additional_flags`

#### Also note that error `Overwriting Docker container privileged flag None with new value False` itself is misleading 


### Environment

- OS:Mac/darwin
