TLS distribution: bind erts socket to localhost
There is no reason for the socket on the erts side of the proxy to
accept connections from other hosts, so let's bind it to the loopback
interface.
Also change {ip, {127,0,0,1}} to {ip, loopback} for the erts side of
the socket for outgoing connections, to avoid hardcoding IPv4.
