route: Set orig_output when redirecting to lwt on locally generated traffic 

orig_output for IPv4 was only set for dsts which hit an input route.
Set it consistently for locally generated traffic as well to allow
lwt to continue the dst_output() path as configured by the nexthop.

Fixes: 2536862311 ("lwt: Add support to redirect dst.input")
