conf, pasta: With --config-net, copy all routes by default

Use the newly-introduced NL_DUP mode for nl_route() to copy all the
routes associated to the template interface in the outer namespace,
unless --no-copy-routes (also implied by -g) is given.

This option is introduced as deprecated right away: it's not expected
to be of any use, but it's helpful to keep it around for a while to
debug any suspected issue with this change.

Otherwise, we can't use default gateways which are not, address-wise,
on the same subnet as the container, as reported by Callum.
