dnsdist: Return a valid unix timestamp for Dynamic Block's `until`

We internally use a timestamp obtained via `CLOCK_MONOTONIC` which
is quite useless to an external observer, so convert it to a normal
unix timestamp in the Lua accessor.

(cherry picked from commit 8cb758ae0c791866f8a6a4f76e41470754d04316)
