Subject: wg-quick: do not set explicit src route for v6 default route

This was only required because clueless network operators were trying to
route fec0::/10 globally, when that range doesn't actually have global
scope. Now that we understand the cause was operator error, we revert
the change here, so that the routing table is kept consistent.

This reverts commit 64e47de870a2f0575b5564a70e5680b48ab83ff9.
