Johnathan Corgan 4a1d583653 fix(gateway): read conntrack over netlink when the proc file is absent
A kernel built without CONFIG_NF_CONNTRACK_PROCFS, such as Ubuntu's, has
no /proc/net/nf_conntrack. The gateway then counted zero sessions for
every mapping, so a mapping still carrying traffic was reclaimed on its
TTL and grace period alone.

When the proc file is absent, the gateway now dumps the IPv6 conntrack
table over NETLINK_NETFILTER, the request conntrack -L makes, and counts
each entry once per distinct destination, the same rule the proc parser
applies. The choice is made on every read, because the proc file appears
only once nf_conntrack is loaded. Any other proc error is still reported
without falling back. When both sources fail, the per-tick warning
carries the netlink error, and the startup line names both errors.

The dump uses netlink-packet-netfilter 0.3, the release built on the
netlink-packet-core 0.8 that rtnetlink already uses.

The gateway suite now expects the netlink source line when the
container has no proc file, and checks that the gateway counts the
session left by the HTTP request through the first virtual IP.

# binaries needed 2.39 installed happily on a system with 2.35 and the daemon
# then could not start. Deriving it also picks up a libdbus floor the hand
# written list lacked, and re-derives per architecture, which matters because
# arm64 links libdbus in all four binaries where amd64 links it in one.
# systemd stays by hand: nothing links it, so nothing can derive it.
