[PATCH] contrib: fix out-of-tree build with jerry-rig.sh

[Benedikt Morbach]

this makes the build system put the objects in ${O}/net/wireguard
instead of ${O}/../../../../../../../../../../../../../../../../../../../../../..${WG}/
(where ${WG} is the full path to wireguard/src), allowing out-of-tree
kernel builds to work with WireGuard jerry-rigged in.
