rpc: add --rpc-payment-allow-free-loopback

Browse source 
This allows RPC coming from the loopback interface to not have
to pay for service. This makes it possible to run an externally
accessible RPC server for payment while also having a local RPC
server that can be run unrestricted and payment free.
