Use link scope for routes

Host scope means "only valid within this host", which is certainly not correct for Xen virtual devices. Link scope means "only valid in the context of this link", which is correct. Fixes: QubesOS/qubes-issues#7123. Suggested-by: Ente <[email protected]> (cherry picked from commit 0220911)
