daemon: introduce host_with_port for identifying sockets

This allows us to share more code between daemons and avoids
having to make additional syscalls for preparing REMOTE_HOST
and REMOTE_PORT in the PSGI env in -httpd.

This will also make supporting HTTP (and NNTP) over Unix sockets
easier in a future commit.
