reduce cache local ports slightly
Just In Case. 1024-65535 seems a bit heavy-handed. 1024 itself
is technically a "reserved" port and shouldn't be used. 65535 is
probably suspicious for breaking an edge case. Also, we make
heavy use of ports in the 3xxx range for varnish itself. In the
net, this reduces the available ephemeral port count from 64512 to
61534. If that's actually an issue, we have bigger issues (also,
the 8x varnish-fe ports should help mitigate this regardless).
