### Is there an existing issue for this?

- [X] I have searched the existing issues

### Current Behavior

The KMS provider `local-kms` don't start on Apple M1 ( arm64 ).

### Expected Behavior

Localstack should use `darwin-arm64` build of `local-kms`.

### How are you starting LocalStack?

With a docker-compose file

### Steps To Reproduce

#### How are you starting localstack (e.g., `bin/localstack` command, arguments, or `docker-compose.yml`)

    docker run -e KMS_PROVIDER=local-kms localstack/localstack

#### Client commands (e.g., AWS SDK code snippet, or sequence of "awslocal" commands)

    awslocal kms list-aliases


### Environment

```markdown
- OS: OSX 12.0.1 ( Apple M1 Pro )
- LocalStack: 0.13.2
```
