journald: implement socket forwarding

This commit adds a new way of forwarding journal messages - forwarding
over a socket.

The socket can be any of AF_INET, AF_INET6, AF_UNIUX or AF_VSOCK.

The address to connect to is retrieved from the "journald.forward_address" credential.

It can also be specified in systemd-journald's unit file with ForwardAddress=
