    rfkill: Use promise to initialize proxy
    
    There's no good reason for waiting for the proxy to be initialized
    to connect signals. In fact, connecting the signal beforehand
    ensures that the handler is in place when the proxy fetches the
    properties, so we don't have to call the handler explicitly.
    
    That in turn will allow us in a follow-up to rely on the signal
    parameters to only process changed properties.
    
    To achieve that by constructing the proxy manually, and then
    initialize it asynchronously in a Promise.
