[PATCH] wg-quick: avoid traffics from momentarily leaking into the tunnel

[Tom Yan]

The wireguard route table ip rule should stay as a NOP until the
`suppress_prefixlength 0 table main` rule is in effect. Therefore,
add the wireguard default route to its route table after the latter
rule is added.
