send: account for route-based MTU
It might be that a particular route has a different MTU than the
interface, via `ip route add ... dev wg0 mtu 1281`, for example. In this
case, it's important that we don't accidently pad beyond the end of the
MTU. We accomplish that in this patch by carrying forward the MTU from
the dst if it exists. We also add a unit test for this issue.
