sni-router: collapse haproxy bind to comma-separated form
Switch to one-line `bind :80,[::]:80` and `bind :443,[::]:443` per
review feedback in #522. The v6only flag was self-documentation, not
load-bearing: with SO_REUSEADDR (HAProxy's default) and bindv6only=0
the kernel routes v4 packets to the more-specific AF_INET socket
regardless. Comment trimmed to match — the v6only paragraph is gone
because v6only itself is gone.
The shorter form also scales more cleanly when adding ports later,
e.g. `bind :8080,[::]:8080` on a new line.
