labgrid-raw-interface: Add permissions

[JoshuaWatt]

Adds support for the helper.yaml file to specify which subcommands users are allowed to execute using labgrid-raw-interface. Denied commands will fail with an error.

The RawNetworkInterfaceDriver is updated to query if the ip command is allowed before attemping to bring the interface up and down on activate/deactivate. This prevents it from erroring out if this behavior is not allowed
